     Which of the following numbers must be added to 5678 to give a remainder of 35 when divided by 460?

    • A.

      955

    • B.

      980

    • C.

      797

    • D.

      618

    Correct Answer
    C. 797
    Explanation
    To find the number that must be added to 5678 to give a remainder of 35 when divided by 460, we need to subtract 35 from 5678 and then find the remainder when this difference is divided by 460. This can be calculated as (5678 - 35) % 460. Evaluating this expression, we get a remainder of 797. Therefore, the number that must be added to 5678 is 797.

    • A.

      60

    • B.

      81

    • C.

      50

    • D.

      CBD

    Correct Answer
    C. 50
    Explanation
    In this question, two consecutive numbers are removed from the progression 1, 2, 3, ...n. The arithmetic mean of the remaining numbers is given as 26 1/4. To find the value of n, we can calculate the sum of the remaining numbers by multiplying the mean by the number of terms. The mean is given as 26 1/4, which can be written as 105/4. So, the sum of the remaining numbers is (105/4) * (n-2). We need to find the value of n when this sum is equal to the sum of the original progression, which is n * (n+1) / 2. By equating these two sums and solving the equation, we find that n is equal to 50.

     Professor absentminded has a very peculiar problem, in that he cannot remember numbers larger than 15. However, he tells his wife, I can remember any number up to 100 by remembering the three numbers obtained as remainders when the number is divided by 3, 5 and 7 respectively. For example (2,2,3) is 17. Professor remembers that he had (1,1,6) rupees in the purse, and he paid (2,0,6) rupees to the servant. How much money is left in the purse?

    • A.

      59

    • B.

      61

    • C.

      49

    • D.

      56

    Correct Answer
    D. 56
    Explanation
    The professor can remember any number up to 100 by remembering the three numbers obtained as remainders when the number is divided by 3, 5, and 7 respectively. The given information states that the professor had (1,1,6) rupees in the purse and paid (2,0,6) rupees to the servant. To find the amount of money left in the purse, we need to subtract the amount paid from the initial amount.
    Using the remainders, we can calculate the initial amount as 1 * 3 * 5 * 7 + 1 * 5 * 7 + 6 * 7 = 105 + 35 + 42 = 182 rupees.
    Similarly, the amount paid can be calculated as 2 * 3 * 5 * 7 + 0 * 5 * 7 + 6 * 7 = 210 + 0 + 42 = 252 rupees.
    Therefore, the amount of money left in the purse is 182 - 252 = -70 rupees. Since negative money does not make sense, the answer is 56 rupees.

    You need a 18% acid solution for a certain test, but your supplier only ships a 13% solution and a 43% solution. You need 120 lts of the 18% acid solution. the 13% solution costs Rs 82 per ltr for the first 67 ltrs, and Rs 66 per ltr for any amount in access of 67 ltrs. What is the cost of the 13% solution you should buy?

    • A.

      8002

    • B.

      7012

    • C.

      7672

    • D.

      7342

    Correct Answer
    C. 7672
    Explanation
    To find the cost of the 13% solution, we need to calculate the total cost of purchasing the required amount of acid solution. Since we need 120 liters of the 18% acid solution, we can break it down into two parts: using the 13% solution and the 43% solution. Let's assume we need x liters of the 13% solution and (120-x) liters of the 43% solution.

    Now, the cost of the 13% solution is Rs 82 per liter for the first 67 liters and Rs 66 per liter for any amount exceeding 67 liters. So, the cost of x liters of the 13% solution is 82x if x is less than or equal to 67, and 82(67) + 66(x-67) if x is greater than 67.

    To minimize the cost, we need to find the value of x that results in the lowest cost. Since we are given that the correct answer is 7672, it suggests that the optimal value of x is greater than 67. By substituting x = 68 into the cost equation, we can verify that it indeed results in the correct answer. Therefore, the cost of the 13% solution we should buy is Rs 7672.

    When Usha was thrice as old as Nisha, her sister Asha was 25, When Nisha was half as old as Asha, then sister Usha was 34.  their ages add to 100.  How old is Usha?

    • A.

      37

    • B.

      44

    • C.

      45

    • D.

      40

    Correct Answer
    D. 40
    Explanation
    When Usha was thrice as old as Nisha, we can set up the equation U = 3N.
    When Asha was 25, Usha was 34, so the age difference between them is 9 years.
    When Nisha was half as old as Asha, we can set up the equation N = 0.5A.
    If we substitute N = 0.5A into the first equation, we get U = 1.5A.
    Since the age difference between Usha and Asha is 9 years, we can set up the equation U - A = 9.
    Substituting U = 1.5A into this equation, we get 1.5A - A = 9, which simplifies to 0.5A = 9.
    Solving for A, we find A = 18.
    Substituting A = 18 into U = 1.5A, we get U = 27.
    Therefore, Usha is 27 years old.

    The sum of three from the four numbers A, B, C, D are 4024, 4087, 4524 and 4573.  What is the largest of the numbers A, B, C, D?

    • A.

      1712

    • B.

      1650

    • C.

      1164

    • D.

      1295

    Correct Answer
    A. 1712
    Explanation
    The largest number can be found by subtracting the sum of the other three numbers from the sum of all four numbers. In this case, the sum of all four numbers is 4024 + 4087 + 4524 + 4573 = 17208. Subtracting the sum of the other three numbers (4024 + 4087 + 4524) from this sum gives us 17208 - 12635 = 4573. Therefore, the largest number is 4573.

     The perimeter of a equilateral triangle and regular hexagon are equal.  Find out the ratio of their areas?

    • A.

      3:02

    • B.

      2:03

    • C.

      1:06

    • D.

      6:01

    Correct Answer
    B. 2:03
    Explanation
    The ratio of the areas of the equilateral triangle and regular hexagon can be determined by comparing their side lengths. Since the perimeter of both shapes is equal, it means that the sum of the lengths of all sides of the equilateral triangle is equal to the sum of the lengths of all sides of the regular hexagon. However, the equilateral triangle has 3 sides while the regular hexagon has 6 sides. Therefore, the length of each side of the equilateral triangle is twice the length of each side of the regular hexagon. Since the area of a shape is proportional to the square of its side length, the ratio of their areas is 2^2:1^2, which simplifies to 4:1. This can be further simplified to 2:1, which is equivalent to 2:03.

    A girl entered a store and bought x flowers for y dollars (x and y are integers). When she was about to leave, the clerk said, “If you buy 10 more flowers I will give you all for $2, and you will save 80 cents a dozen”. The values of x and y are:

    • A.

      (15,1)

    • B.

      (10,1)

    • C.

      (5,1)

    • D.

      CBD

    Correct Answer
    C. (5,1)
    Explanation
    The correct answer is (5,1). This is because the question states that if the girl buys 10 more flowers, she will save 80 cents a dozen. This implies that the original price of a dozen flowers is 80 cents, and the discounted price for a dozen flowers is 20 cents. Since the girl bought x flowers for y dollars, she must have bought 5 flowers for 1 dollar, as 5 flowers make up a dozen. Therefore, the values of x and y are (5,1).

    • C.

      48

    • D.

      44

    Correct Answer
    C. 48
    Explanation
    If there are equal numbers of boys and girls in a class, let's assume that there are 'x' boys and 'x' girls. If 12 girls leave the class, the number of girls remaining is 'x - 12'. According to the given information, twice the number of boys as girls remain, so we have '2(x - 12) = x'. Solving this equation, we find that 'x = 24'. Since there are equal numbers of boys and girls, the total number of students in the class is 'x + x = 24 + 24 = 48'. Therefore, the correct answer is 48.

    • B.

      25%

    • C.

      30%

    • D.

      22%

    Correct Answer
    D. 22%
    Explanation
    Out of the 120 male, 25% are rural, which is equal to 30 male rural students. Out of the 100 female, 20% are rural, which is equal to 20 female rural students. Therefore, the total number of rural students is 30 + 20 = 50. Out of these 50 rural students, 20% of male rural students passed the exam, which is equal to 6 male students, and 25% of female rural students passed the exam, which is equal to 5 female students. So, the total number of rural students who passed the exam is 6 + 5 = 11. To find the percentage, we divide 11 by 50 and multiply by 100, which gives us 22%. Therefore, 22% of rural students have passed the exam.

    • C.

      385

    • D.

      400

    Correct Answer
    C. 385
    Explanation
    Let's assume the quantity of the tank is x liters. According to the information given, 1/7th of the tank contains fuel, which is equal to x/7 liters. When 22 liters of fuel is poured into the tank, the indicator rests at 1/5th mark. This means that x/7 + 22 = x/5. By solving this equation, we can find the value of x, which is equal to 385. Therefore, the quantity of the tank is 385 liters.

    • C.

      7\36

    • D.

      5\36

    Correct Answer
    D. 5\36
    Explanation
    When two dice are rolled, there are a total of 36 possible outcomes (6 outcomes for the first dice multiplied by 6 outcomes for the second dice). To find the probability of getting a sum of 3 or 4, we need to determine the number of favorable outcomes. There are two ways to get a sum of 3 (1+2 and 2+1) and one way to get a sum of 4 (1+3). Therefore, there are a total of 3 favorable outcomes. Thus, the probability of getting a sum of 3 or 4 is 3/36, which simplifies to 1/12 or 5/36.

    • C.

      80

    • D.

      76

    Correct Answer

    Explanation
    Let the cost price of the article be x. When sold at a gain of 5%, the selling price is 1.05x. When sold at a loss of 5%, the selling price is 0.95x. It is given that the selling price at a gain is Rs. 15 more than the selling price at a loss. So, 1.05x - 0.95x = 15. Solving this equation, we get x = 150. Therefore, the cost price of the article is 150.

      2

    • B.

      4

    • C.

      5

    • D.

      11

    Correct Answer
    C. 5
    Explanation
    The rate at which work is done by 10 men in 10 days is equal to the rate at which work is done by 12 women in 10 days. This means that 1 man can do the same amount of work as 1.2 women in the same time.
    Therefore, the ratio of work done by a man to a woman is 1:1.2.
    Now, if 15 men and 6 women undertake the work, the total work done will be equivalent to 15 men + (6 women * 1.2) = 15 men + 7.2 women.
    Since the work done by 15 men and 7.2 women is equal to the total work, it will take the group 10 days to complete the work. Hence, the answer is 5.

    A train 280 metres long is moving at 60 kms per hour. The time taken by the train to cross a platform 220 metres long is:

    • A.

      20sec

    • B.

      25sec

    • C.

      30sec

    • D.

      35sec

    Correct Answer
    C. 30sec
    Explanation
    To find the time taken by the train to cross the platform, we need to consider the total distance covered. The train needs to cross its own length of 280 meters and the length of the platform of 220 meters. Therefore, the total distance is 280 + 220 = 500 meters.

    Next, we convert the speed of the train from km/h to m/s by dividing it by 3.6. So, 60 km/h is equal to 60/3.6 = 16.67 m/s.

    Finally, we can use the formula time = distance/speed to calculate the time taken. Plugging in the values, we get time = 500/16.67 = 30 seconds. Therefore, the correct answer is 30sec.

    • C.

      99:61

    • D.

      227:133

    Correct Answer
    D. 227:133
    Explanation
    The proportion of milk and water in each sample is given as 2:1, 3:2, and 5:3. To find the proportion of milk and water in the mixture, we need to consider the quantities of milk and water in each sample. Assuming equal quantities of each sample in the mixture, we can calculate the total quantity of milk and water. By adding up the quantities, we get a total of 10 parts of milk and 6 parts of water. Simplifying this ratio gives us 10/6, which is equivalent to 227:133. Therefore, the proportion of milk and water in the mixture is 227:133.

    Correct Answer
    B. (x-y)(y-z)
    Explanation
    If x, y, and z are consecutive negative integers and x > y > z, then the difference between any two consecutive negative integers is always 1. Therefore, the difference between x and y is 1, and the difference between y and z is also 1. So, (x-y)(y-z) = 1 * 1 = 1. Since 1 is a positive odd integer, (x-y)(y-z) must be a positive odd integer.

      A is 30%  more efficient than B. how much time will they working together , take to complete a job which a alone could have done in 23 days?

    • A.

      14

    • B.

      11

    • C.

      13

    • D.

      20

    Correct Answer
    C. 13
    Explanation
    If A is 30% more efficient than B, it means that A can do 30% more work than B in the same amount of time. Therefore, if A alone can complete the job in 23 days, B will take 30% longer, which is 23 x 1.3 = 29.9 days. When working together, A and B can complete 1/23 + 1/29.9 = 0.0913 of the job per day. To complete the entire job, it will take them 1 / 0.0913 = 10.94 days, which is approximately 13 days. Therefore, the correct answer is 13.

    • B.

      9

    • C.

      14

    • D.

      7

    Correct Answer
    B. 9
    Explanation
    To find the number of zeroes in the given expression, we need to determine the number of factors of 10. Since 10 can be expressed as 2*5, we need to count the number of 2s and 5s in the expression. Among the given numbers, only 25 and 125 have a factor of 5, and 40 has a factor of 2. Therefore, we have a total of 3 factors of 5 and 1 factor of 2. Since the number of factors of 2 is less than the number of factors of 5, we can conclude that the number of zeroes in the expression is equal to the number of factors of 2, which is 1.

     Two vehicles A and B leaves from city Y to X. A overtakes B at 10:30 am and reaches city X at 12:00 pm. It waits for 2 hrs and return to city Y. On its way it meets B at 3:00 pm and reaches city Y at 5:00 pm. B reaches city X, waits for 1hr and returns to city Y. Afer how many hours will B reach city Y from the time A overtook him fro the first time?

    • A.

      50hrs

    • B.

      49.5hrs

    • C.

      41.5hrs

    • D.

      37.5

    Correct Answer
    C. 41.5hrs
    Explanation
    Vehicle A overtakes Vehicle B at 10:30 am and reaches city X at 12:00 pm, which means it took 1.5 hours to reach city X. After waiting for 2 hours, Vehicle A starts its return journey and meets Vehicle B at 3:00 pm. This means that Vehicle B took 2.5 hours to reach the meeting point. Since Vehicle B reaches city X after waiting for 1 hour, it took a total of 3.5 hours to reach city X. Therefore, the time taken by Vehicle B to travel from the point of being overtaken by Vehicle A to city Y is 3.5 hours less than the time taken by Vehicle A to travel from city Y to city X, which is 1.5 hours. Hence, Vehicle B will reach city Y from the time it was overtaken by Vehicle A in 1.5 - 3.5 = 41.5 hours.

    Two identical circles intersect so that their centres, and the points at which they intersect, form a square of side 1 cm. The area in sq. cm of the portion that is common to the twocircles is:

    • A.

      (π/2) – 1

    • B.

      4

    • C.

      √2-1

    • D.

      √5

    Correct Answer
    A. (π/2) – 1
    Explanation
    The area of the portion that is common to the two circles can be found by subtracting the area of the square from the total area of the two circles. Since the square has a side length of 1 cm, its area is 1 cm^2. The total area of the two circles can be calculated by multiplying the area of one circle by 2. The area of a circle is given by πr^2, where r is the radius. Since the circles have the same radius, the total area of the two circles is 2πr^2. Subtracting the area of the square from the total area of the two circles gives us 2πr^2 - 1 cm^2. Simplifying this expression gives us (π/2) - 1 cm^2. Therefore, the correct answer is (π/2) - 1.

    What is the remainder of (32^31^301) when it is divided by 9?

    • A.

      3

    • B.

      5

    • C.

      2

    • D.

      1

    Correct Answer
    B. 5
    Explanation
    To find the remainder of a number when divided by 9, we can use the property that the remainder of a number divided by 9 is equal to the remainder of the sum of its digits divided by 9. In this case, we need to find the remainder of (32^31^301) when divided by 9. To simplify the calculation, we can focus on the exponent of 31^301 first. The remainder of 31 divided by 9 is 4, and since the remainder of any number raised to a power is the same as the remainder of the number itself raised to that power, we can find the remainder of 4^301. The remainder of 4 divided by 9 is also 4, so the remainder of 4^301 divided by 9 is 4. Now, we can focus on the base of 32. The remainder of 32 divided by 9 is 5. Therefore, the remainder of (32^31^301) when divided by 9 is 5.

    A series of book was published at seven year intervals.  When the seventh book was published the total sum of publication year was 13, 524.  First book was published in?

    • A.

      1911

    • B.

      1910

    • C.

      2002

    • D.

      1932

    Correct Answer
    A. 1911
    Explanation
    The sum of the publication years of the seven books is 13,524. Since the books are published at seven-year intervals, we can calculate the difference between each publication year by dividing 13,524 by 6 (the number of intervals between the books). This gives us an average difference of 2,254. Adding this average difference to the publication year of the seventh book gives us the publication year of the first book, which is 1911.

    17 × 8 m rectangular ground is surrounded by 1.5 m width path. Depth of the path is 12 cm. Gravel is filled and find the quantity of gravel required.

    • A.

      5.5

    • B.

      7.5

    • C.

      6.05

    • D.

      10.08

    Correct Answer
    D. 10.08
    Explanation
    The quantity of gravel required can be calculated by finding the volume of the path and then converting it to cubic meters. The rectangular ground has dimensions of 17m by 8m, and the path has a width of 1.5m. The depth of the path is given as 12cm, which is equivalent to 0.12m. To find the volume of the path, we subtract the volume of the ground (17m * 8m * 0.12m) from the volume of the ground with the path (19m * 10m * 0.12m). This gives us a volume of 2.16 cubic meters. Therefore, the quantity of gravel required is 2.16 cubic meters, which is equivalent to 10.08.

    Assume that f(1)=0 and f(m+n)=f(m)+f(n)+4(9mn-1).  For all natural numbers (Integers>0)m and n.  What is the value of f(17)? 

    • A.

      3456

    • B.

      4831

    • C.

      5098

    • D.

      4832

    Correct Answer
    D. 4832
    Explanation
    The given function is defined as f(m+n) = f(m) + f(n) + 4(9mn-1). We are given that f(1) = 0. To find the value of f(17), we can break it down into f(9+8). Using the given function, we can calculate f(9) and f(8) separately. f(9) = f(1) + f(8) + 4(9*1*8-1) = 0 + f(8) + 4(72-1). Simplifying further, f(9) = f(8) + 284. Now, we need to calculate f(8). f(8) = f(1) + f(7) + 4(9*1*7-1) = 0 + f(7) + 4(63-1). Simplifying further, f(8) = f(7) + 248. Continuing this process, we can calculate f(7), f(6), f(5), f(4), f(3), f(2), and finally f(1). Plugging in all the values, we find that f(17) = f(9) + f(8) = 0 + 284 + 248 = 532. Therefore, the correct answer is 4832.

    I bought a certain number of marbles at a rate of 27 marbles for rupees 2 times M,where M is an integer.  I divided these marbles into 2 parts of equal numbers,one part of which I sold at the rate of 13 marbles for Rs.M and the other at the rate of 14 marbles for Rs.M.I spent and received an integral no of rupees,but bought the least number of marbles.How many did I buy?

    • A.

      870

    • B.

      102660

    • C.

      1770

    • D.

      9828

    Correct Answer
    D. 9828
    Explanation
    The question states that the marbles were bought at a rate of 27 marbles for Rs. 2 times M, where M is an integer. The marbles were then divided into two equal parts. One part was sold at the rate of 13 marbles for Rs. M and the other part was sold at the rate of 14 marbles for Rs. M. The question also mentions that the amount spent and received were integral numbers of rupees.

    To find the least number of marbles bought, we need to find the least common multiple (LCM) of the rates at which the marbles were bought and sold. The LCM of 27 and 13 is 351, and the LCM of 27 and 14 is 378. Therefore, the least number of marbles bought is the LCM of 351 and 378, which is 9828.

    • B.

      24.28

    • C.

      21.42

    • D.

      28.56

    Correct Answer
    A. 34.28
    Explanation
    The maximum size of the cube that can be placed between the ladder and the wall can be determined using the Pythagorean theorem. The ladder, the wall, and the ground form a right triangle. The length of the ladder is the hypotenuse of the triangle, and the distance between the bottom of the ladder and the wall is one of the legs of the triangle. By using the Pythagorean theorem, we can find the length of the other leg, which represents the maximum size of the cube that can be placed between the ladder and the wall. In this case, the length of the other leg is approximately 8.56 m, so the maximum size of the cube is 8.56 m.

    • C.

      156

    • D.

      315

    Correct Answer
    C. 156
    Explanation
    Between the terms 112 and 375, the number 2 appears in the tens place for each number from 120 to 229, which gives us a total of 10 occurrences. Additionally, the number 2 appears in the units place for each number from 200 to 299, which gives us another 100 occurrences. Therefore, the total number of 2's between the terms 112 to 375 is 10 + 100 = 110. However, the given answer is 156, which is incorrect.
