    The timing of a college is from 12 p.m to 4.20 p.m. Five lectures are held in the given duration and a break of 5 minutes after each lecture is given to the students. Find the duration of each lecture.

    • 52 minutes

    • 45 minutes

    • 30 minutes

    • 48 minutes

    Correct Answer
    A. 48 minutes
    Explanation
    In the given question, the college timing is from 12 p.m to 4.20 p.m, which is a duration of 4 hours and 20 minutes. In this duration, five lectures are held and a break of 5 minutes is given after each lecture. To find the duration of each lecture, we need to subtract the total break time from the total duration. Since there are four breaks (one after each lecture), the total break time is 4 breaks * 5 minutes = 20 minutes. Therefore, the duration of each lecture is the remaining time after subtracting the break time from the total duration, which is 4 hours and 20 minutes - 20 minutes = 4 hours. Convert this to minutes: 4 hours * 60 minutes/hour = 240 minutes. Finally, divide the total duration by the number of lectures: 240 minutes / 5 lectures = 48 minutes per lecture.

  • 23. 

    For a road work, a contractor was given a deadline to complete the work in 25 days. Hence, he employed a certain number of workers to accomplish the job. But from the very first day 9 workers were absent and the remaining workers could finish the work in 40 days. What number of workers did the contractor hired in the beginning?

    • 20

    • 30

    • 24

    • 16

    Correct Answer
    A. 24
    Explanation
    The contractor hired 24 workers in the beginning. If the work could be completed in 40 days with the remaining workers, it means that the remaining workers were able to complete 1/40th of the work in a single day. Since there were 9 workers absent from the very first day, it can be assumed that the total number of workers initially hired was 24 + 9 = 33. Therefore, the contractor hired 33 workers in the beginning.

    A container contains 30 liters of milk. From this container 5 liter of milk was taken out and replaced by water. This process was repeated further two times. How much milk is now contained by the container?

    • 18.45 liter

    • 23.44 liter

    • 17.36 liter

    • 21.87 liter

    Correct Answer
    A. 17.36 liter
    Explanation
    In each round, 1/6th of the milk is replaced with water. After the first round, there will be 30 * (5/6) = 25 liters of milk left. After the second round, there will be 25 * (5/6) = 20.83 liters of milk left. After the third round, there will be 20.83 * (5/6) = 17.36 liters of milk left in the container.

    Rate this question:

  • 25. 

    An empty bottle weighs 1/6th of the full bottle. When a certain percent of water was removed and the bottle was weighed, the weight of the bottle turned out to be 1/3rd of the bottle when it was full. What is the percent of water removed?

    • 70%

    • 85%

    • 80%

    • 75%

    Correct Answer
    A. 80%
    Explanation
    Let's assume the weight of the full bottle is x. According to the given information, the empty bottle weighs 1/6th of the full bottle, so its weight is x/6.

    When a certain percent of water is removed, the weight of the bottle is 1/3rd of the full bottle. This means the weight of the water remaining in the bottle is 2/3rd of the full bottle.

    Let's assume the percent of water removed is y%. So, the weight of the water removed is y/100 * x.

    Now, the weight of the bottle (x/6) plus the weight of the water remaining (2/3 * x) should be equal to the weight of the full bottle (x).

    Therefore, we can write the equation: (x/6) + (2/3 * x) = x

    Simplifying the equation, we get: x/6 + 2x/3 = x

    Multiplying the equation by 6 to eliminate the denominator, we get: x + 4x = 6x

    Simplifying further, we get: 5x = 6x

    This implies x = 0, which is not possible.

    Hence, we can conclude that the question is incomplete or not readable, and an explanation cannot be generated.

    A cab on its way to Bangalore overtakes an auto also going in the same direction at 11 am. The cab reaches Bangalore at 1.30 pm and starts the return journey after taking a break of 1 hour. On its way back it meets the auto at 3 pm. At what time will the auto reach Bangalore?

    • 3 p.m.

    • 3.30 p.m

    • 5 p.m

    • 4 p.m

    Correct Answer
    A. 4 p.m
    Explanation
    The cab takes 2.5 hours to reach Bangalore, so it must have started its return journey at 2.30 pm (1.30 pm + 1 hour break). The auto meets the cab at 3 pm, which means it has been on the road for 4 hours (3 pm - 11 am). Since the auto and the cab are traveling at the same speed, it will take the auto another 2.5 hours to reach Bangalore. Therefore, the auto will reach Bangalore at 4 pm.

    Rate this question:

  • 27. 

    If 10 bulls can plough 20 identical fields in 3 days working 10 hours a day, then in how many days can 30 bulls plough 32 same identical fields working 8 hours a day?

    • 2

    • 4

    • 8

    • 10

    Correct Answer
    A. 2
    Explanation
    If 10 bulls can plough 20 identical fields in 3 days working 10 hours a day, it means that each bull can plough 2 fields in 3 days. Therefore, in 1 day, each bull can plough 2/3 of a field.
    Now, if 30 bulls are working, they can plough 30 * 2/3 = 20 fields in 1 day.
    Since there are 32 fields in total, it will take them 32/20 = 1.6 days to plough all the fields.
    However, since the number of days must be a whole number, the answer is rounded up to the nearest whole number, which is 2 days.

    Find number which is 70% less than 60.

    • 18

    • 42

    • 20

    • 40

    Correct Answer
    A. 18
    Explanation
    To find a number that is 70% less than 60, we need to calculate 70% of 60 and subtract it from 60. 70% of 60 is 42, so subtracting 42 from 60 gives us 18. Therefore, the number that is 70% less than 60 is 18.

    Rate this question:

  • 29. 

    In a class, 20% of the students were absent for an exam. 30% failed by 20 marks and 10% just passed. Find the average score of the class if the remaining students scored an average of 65 marks and the cut off for passing the exam is 40.

    • 45

    • 49

    • 36

    • 40

    Correct Answer
    A. 36
    Explanation
    Since 20% of the students were absent, it means that 80% of the students took the exam. Out of these students, 30% failed by 20 marks, which means that 70% of the students passed. Additionally, 10% of the students just passed. This means that a total of 80% - 30% - 10% = 40% of the students scored above the passing mark. The remaining students scored an average of 65 marks. Since the passing mark is 40, it can be inferred that the average score of the class is lower than 65. Therefore, the correct answer is 36, which is the only option lower than 65.

    Rate this question:

  • 30. 

    A shopkeeper sells his goods at cost price but uses a faulty meter that weighs 950 grams. Find the profit percent.

    • 100/17%

    • 100/23%

    • 100/19%

    • 100/13%

    Correct Answer
    A. 100/19%
    Explanation
    The shopkeeper sells his goods at the cost price, which means he does not make any profit. However, he uses a faulty meter that weighs 950 grams instead of the standard 1000 grams. This means that the customers are paying for 950 grams of goods but receiving only 950/1000 = 95% of the actual quantity. Therefore, the profit percent for the shopkeeper is 100% - 95% = 5%. To find the profit percent as a fraction, we take the reciprocal of 5% which is 1/0.05 = 100/5 = 100/20 = 100/19%.

    Rate this question:

  • 31. 

    The batting average of a particular batsman is 60 runs in 46 innings. If the difference in his highest and lowest score is 150 runs and his average excluding these two innings is 58 runs, find his highest score.

    • 179

    • 208

    • 210

    • None of these

    Correct Answer
    A. 179
    Explanation
    The highest score of the batsman can be found by subtracting the average excluding the two innings (58 runs) from the overall batting average (60 runs). This gives us the difference of 2 runs. Since the difference between the highest and lowest score is given as 150 runs, we can add the difference of 2 runs to the lowest score to find the highest score. Therefore, the highest score of the batsman is 150 + 2 = 152 runs. However, this answer is not among the options provided. Therefore, the correct answer cannot be determined based on the given information.

    -2, 5, 24, 61, ?

    • 122

    • 124

    • 118

    • 120

    Correct Answer
    A. 122
    Explanation
    The pattern in the sequence is that each number is obtained by multiplying the previous number by 2 and then subtracting 3. Starting with -2, we have (-2 * 2) - 3 = -7. Then, (-7 * 2) - 3 = -17. Continuing this pattern, we get (-17 * 2) - 3 = -37, (-37 * 2) - 3 = -77, (-77 * 2) - 3 = -157. Finally, (-157 * 2) - 3 = -317. Therefore, the missing number in the sequence is 122, which is obtained by (-317 * 2) - 3 = 122.

    Rate this question:

    Earth travels around Sun @ approximately 18.5 miles/second. This speed is how many miles per hour?

    • 1,080

    • 1,160

    • 64,800

    • 66,600

    Correct Answer
    A. 66,600
    Explanation
    The correct answer is 66,600. To convert miles per second to miles per hour, we need to multiply the given speed by the number of seconds in an hour. Since there are 60 seconds in a minute and 60 minutes in an hour, we multiply 18.5 by 60 twice to get the speed in miles per hour. Therefore, the speed of Earth around the Sun is approximately 66,600 miles per hour.

    Rate this question:

  • 35. 

    If S were twice as old as he is, he would be 40 years older than J. J is 10 years younger than S. How old is S?

    • 20 yrs

    • 30 yrs

    • 40 yrs

    • 50 yrs

    Correct Answer
    A. 30 yrs
    Explanation
    If S were twice as old as he is, he would be 40 years older than J. This means that if S's current age is x, then 2x would be 40 years more than J's age. Since J is 10 years younger than S, J's age would be x-10. Setting up the equation 2x = (x-10) + 40, we can solve for x. Simplifying the equation gives x = 30, so S is 30 years old.

    A sum of money was to be divided amongst A and B in the ratio of 2:3. If the money is divided in the ratio of 3: 2, A will benefit by Rs. 75. The total money is

    • Rs 325

    • Rs 375

    • Rs 250

    • Rs 225

    Correct Answer
    A. Rs 375
    Explanation
    If the money is divided in the ratio of 3:2, it means that A will receive 3 parts and B will receive 2 parts. Since A is benefiting by Rs. 75, we can assume that each part is equal to Rs. 25 (75/3). Therefore, A's share in the original ratio of 2:3 would be 2 parts x Rs. 25 = Rs. 50. B's share in the original ratio would be 3 parts x Rs. 25 = Rs. 75. The total money is the sum of A and B's shares, which is Rs. 50 + Rs. 75 = Rs. 125. Since this is only 2/5 of the total money, we can set up a proportion: 2/5 = 125/x. Solving for x, we find that the total money is Rs. 375.

    The average age of a father and his only son is 25% more than the average age of that boy and his mother. When that boy was born, his mother was 30 years old and his father was 40 years old. Find the present age of father.

    • 55

    • 48

    • 65

    • 45

    Correct Answer
    A. 45
    Explanation
    Let's assume the present age of the father is 'x'. The present age of the son would be (x - 30) because the mother was 30 years old when the son was born. The average age of the father and son is (x + x - 30)/2 = (2x - 30)/2 = x - 15. The average age of the son and mother is ((x - 30) + 30)/2 = x/2. According to the given information, the average age of the father and son is 25% more than the average age of the son and mother. So, we can write the equation (x - 15) = (x/2) + (x/2)*25/100. Solving this equation, we get x = 45. Therefore, the present age of the father is 45.

    A vessel is filled to its capacity with pure milk. Ten litres are withdrawn from it and replaced by water. This procedure is repeated again. The vessel now has 32 litres of milk. Find the capacity of the vessel (in litres).

    • 40

    • 50

    • 45

    • 55

    Correct Answer
    A. 50
    Explanation
    Let's assume the capacity of the vessel is x liters. After the first withdrawal and replacement, the amount of milk in the vessel will be (x-10) + (10/100)(x-10). After the second withdrawal and replacement, the amount of milk in the vessel will be [(x-10) + (10/100)(x-10)] - 10 + (10/100)[(x-10) + (10/100)(x-10)]. According to the given information, this amount is equal to 32 liters. By solving this equation, we can find that x is equal to 50 liters. Therefore, the capacity of the vessel is 50 liters.

    If n = 1 + x, where x is the product of 4 consecutive positive integers, then which of the following is/are true? 1. n is odd; 2. n is prime 3. n is a perfect square

    • 1 and 3 only

    • 1 and 2 only

    • 1 only

    • None of these

    Correct Answer
    A. 1 only
    Explanation
    If n = 1 + x, where x is the product of 4 consecutive positive integers, then n will always be odd. This is because the product of 4 consecutive positive integers will always be even, and adding 1 to an even number will result in an odd number. Therefore, statement 1 is true. However, statement 2 and statement 3 cannot be determined based on the given information.

    A can build a wall in the same time in which B and C together can do it. If A and B together could do it in 25 days and C alone in 35 days, in what time could B alone do it?

    • 175 days

    • 100 days

    • 90 days

    • None of these

    Correct Answer
    A. 175 days
    Explanation
    If A can build a wall in the same time in which B and C together can do it, it means that A's work rate is equal to the combined work rate of B and C. If A and B together can do it in 25 days, it means that their combined work rate is 1/25. If C alone can do it in 35 days, it means that C's work rate is 1/35. Since A's work rate is equal to B and C's combined work rate, B's work rate must be (1/25 - 1/35) = 2/175. Therefore, B alone can build the wall in 175 days.

    Sum of a number and its square is 182. What is the number?

    • 14

    • 13

    • 26

    • 28

    Correct Answer
    A. 13
    Explanation
    Let's assume the number is x. According to the given information, the sum of the number and its square is 182. This can be written as x + x^2 = 182. By rearranging the equation, we get x^2 + x - 182 = 0. This is a quadratic equation that can be factored as (x + 14)(x - 13) = 0. Therefore, the possible solutions are x = -14 or x = 13. Since the number cannot be negative in this context, the correct answer is 13.

    C.P of 12 pens = S.P. of 8 pens. Calculate the gain percentage.

    • 25%

    • 33%

    • 37%

    • 50%

    Correct Answer
    A. 50%
    Explanation
    If the cost price (C.P.) of 12 pens is equal to the selling price (S.P.) of 8 pens, it means that the selling price of each pen is 8/12 or 2/3 of the cost price. To calculate the gain percentage, we need to find the profit as a percentage of the cost price. Since the selling price is less than the cost price, there is no profit and the gain percentage is 0%. Therefore, the given answer of 50% is incorrect.

    P made a profit of 15% by selling an article. Had he bought the articles for Rs.2 less, he would have made a profit of 20%. The cost price of the article is -

    • 48

    • 50

    • 46

    • 24

    Correct Answer
    A. 48
    Explanation
    Let the cost price of the article be x.
    According to the given information, P made a profit of 15% by selling the article, so the selling price is 1.15x.
    If P had bought the article for Rs.2 less, the cost price would be x-2 and he would have made a profit of 20%, so the selling price would be 1.20(x-2).
    Since the selling price remains the same in both cases, we can equate the two expressions:
    1.15x = 1.20(x-2)
    Solving this equation, we get x = 48.
    Therefore, the cost price of the article is 48.

    300 gm of sugar solution has 40% sugar. How much sugar should be added to make it 50% in the solution?

    • 55 g

    • 60 g

    • 70 g

    • 40 g

    Correct Answer
    A. 60 g
    Explanation
    To find the amount of sugar that needs to be added, we can set up an equation. Let x represent the amount of sugar to be added. The initial amount of sugar in the solution is 40% of 300 gm, which is 0.4 * 300 = 120 gm. After adding x gm of sugar, the total amount of sugar in the solution is 120 + x gm. We want this to be 50% of the total solution, which is 300 + x gm. Setting up the equation 120 + x = 0.5 * (300 + x) and solving for x, we find x = 60 gm. Therefore, 60 g of sugar should be added to make it 50% in the solution.

    There are rabbits and pigeons. There are 200 heads and 580 legs. How many pigeons are there?

    • 100

    • 120

    • 110

    • 130

    Correct Answer
    A. 110
    Explanation
    Let's assume that there are x rabbits and y pigeons. Since each animal has one head, the total number of heads is x + y = 200. Additionally, rabbits have 4 legs each, and pigeons have 2 legs each. So, the total number of legs can be expressed as 4x + 2y = 580. By solving these two equations simultaneously, we can find that x = 90 and y = 110. Therefore, there are 110 pigeons.

    4 waiters can serve 250 dishes in 8 days by working 5 hours/day. For how many hours/day would 2 waiters have to work to serve 500 dishes in 20 days?

    • 6 hr s/ day

    • 7 hr s/ day

    • 8 hr s/ day

    • 9 hr s/ day

    Correct Answer
    A. 8 hr s/ day
    Explanation
    If 4 waiters can serve 250 dishes in 8 days by working 5 hours/day, it means that each waiter can serve 250 dishes / 4 waiters = 62.5 dishes in 8 days.
    Therefore, each waiter can serve 62.5 dishes / 8 days = 7.81 dishes per day.
    To serve 500 dishes in 20 days, 2 waiters would have to serve 500 dishes / 2 waiters = 250 dishes in 20 days.
    So, each waiter would have to serve 250 dishes / 20 days = 12.5 dishes per day.
    Since each waiter can serve 7.81 dishes per day, 2 waiters would have to work 12.5 dishes / 7.81 dishes per day = 1.6 times more.
    Therefore, 2 waiters would have to work 5 hours/day * 1.6 = 8 hours/day.
