    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 4
    Explanation
    The correct answer is option 4. To find the original number of apples, we can set up the equation: 40% of x = 420. Solving for x, we get x = 420 / 0.4 = 1050. Therefore, the original number of apples is 1050 - 420 = 700.

    A card is drawn from a pack of 52 cards. The probability of getting a queen of club or a king of heart is: 1 1 13 2 2 13 3 1 26 4. 1 52

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 3
    Explanation
    The probability of getting a queen of club or a king of heart can be calculated by adding the probabilities of getting each card separately. There is only 1 queen of club in a deck of 52 cards, so the probability of getting a queen of club is 1/52. Similarly, there is only 1 king of heart in a deck of 52 cards, so the probability of getting a king of heart is also 1/52. Therefore, the probability of getting a queen of club or a king of heart is (1/52) + (1/52) = 1/26.

    In a two-digit, if it is known that its unit's digit exceeds its ten's digit by 2 and that the product of the given number and the sum of its digits is equal to 144, then the number is: 1. 24 2. 26 3. 42 4. 46

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 1
    Explanation
    The correct answer is 24. The unit's digit exceeds the ten's digit by 2, which means the ten's digit is 2 less than the unit's digit. Let's assume the unit's digit is x, then the ten's digit would be x-2. The number can be represented as 10(x-2) + x = 144. Simplifying this equation, we get 11x - 20 = 144. Solving for x, we find that x = 24. Therefore, the number is 24.

      How much time will it take for an amount of Rs. 450 to yield Rs. 81 as interest at 4.5% per annum of simple interest? 1. 3.5 years 2. 4 years 3. 4.5 years 4. 5 years

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 2
    Explanation
    To calculate the time it will take for an amount of Rs. 450 to yield Rs. 81 as interest at 4.5% per annum of simple interest, we can use the formula: Time = (Simple Interest * 100) / (Principal * Rate). Plugging in the given values, we get Time = (81 * 100) / (450 * 4.5) = 4 years. Therefore, the correct answer is option 2.

      Two ships are sailing in the sea on the two sides of a lighthouse. The angle of elevation of the top of the lighthouse is observed from the ships are 30° and 45° respectively. If the lighthouse is 100 m high, the distance between the two ships is: 1. 173 m 2. 200 m 3. 273 m 4. 300 m

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 3
    Explanation
    The distance between the two ships can be found using trigonometry. Let's assume that the distance between the lighthouse and the ship with the 30° angle of elevation is x, and the distance between the lighthouse and the ship with the 45° angle of elevation is y.

    Using the tangent function, we can set up the following equations:
    tan(30°) = 100/x
    tan(45°) = 100/y

    Solving these equations, we find that x = 100/tan(30°) and y = 100/tan(45°).

    The distance between the two ships is the sum of x and y, which is equal to 100/tan(30°) + 100/tan(45°).

    Calculating this expression gives us the answer of 273 m.

No improvement  

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer

    The correct alternative is "in crushing" because it accurately conveys the idea that the protestant leaders joined the princes in the act of crushing the serfs. The phrase "in crushing" suggests that the protestant leaders actively participated in the action of crushing the serfs, rather than simply being present at the scene. This alternative improves the clarity and specificity of the sentence.

      In how many different ways can the letters of the word 'LEADING' be arranged in such a way that the vowels always come together? 1. 360 2. 480 3. 720 4. 5040    

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 3
    Explanation
    The correct answer is 720. To find the number of ways the letters of the word 'LEADING' can be arranged such that the vowels always come together, we can treat the group of vowels (EA) as a single entity. This reduces the problem to arranging the letters LNDG(EA) in a linear fashion. There are 6 letters in total, with 2 identical vowels (E) and 4 distinct consonants (LNDG). Therefore, the number of arrangements is 6!/2! = 720.

      The ratio between the perimeter and the breadth of a rectangle is 5 : 1. If the area of the rectangle is 216 sq. cm, what is the length of the rectangle? 1. 16 cm 2. 18 cm 3. 24 cm 4. Data inadequate    

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 2
    Explanation
    The length of the rectangle can be found by using the formula for the area of a rectangle, which is length multiplied by breadth. Since the area is given as 216 sq. cm and the ratio between the perimeter and breadth is 5:1, we can set up the equation 5x + 2x = 216, where x represents the breadth. Solving this equation, we find that x = 24. Therefore, the length of the rectangle is 2x = 2 * 24 = 48 cm.

    A. Option 3
    Explanation
    The H.C.F. (Highest Common Factor) of two numbers is the largest number that divides both of them without leaving a remainder. In this case, the H.C.F. is 23.

    The L.C.M. (Least Common Multiple) of two numbers is the smallest number that is divisible by both of them. The L.C.M. of the two numbers in this case has two factors, 13 and 14.

    To find the larger of the two numbers, we need to find the product of the H.C.F. and the L.C.M., and then divide it by the smaller number.

    So, (23 * L.C.M.) / 13 = larger number.

    Since the L.C.M. has a factor of 13, we can cancel it out, leaving us with (23 * L.C.M.) / 1 = larger number.

    Therefore, the larger number is 23 * L.C.M., which is 23 * 14 = 322.

    Hence, the correct answer is option 3.

  • 35. 

    A father said to his son, "I was as old as you are at the present at the time of your birth". If the father's age is 38 years now, the son's age five years back was: 1. 14 years 2. 19 years 3. 33 years 4. 38 years

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 1
    Explanation
    The father's age at the time of the son's birth was 38 years. This means that the son's age at present is also 38 years. Therefore, five years back, the son's age would have been 38 - 5 = 33 years.

      Two trains, each 100 m long, moving in opposite directions, cross each other in 8 seconds. If one is moving twice as fast the other, then the speed of the faster train is: 1. 30 km/hr 2. 45 km/hr 3. 60 km/hr 4. 75 km/hr

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 3
    Explanation
    The length of both trains combined is equal to the distance they travel in 8 seconds. Since they are moving in opposite directions, their relative speed is the sum of their individual speeds. Let the speed of the slower train be x m/s. The speed of the faster train is 2x m/s. Therefore, the total distance covered in 8 seconds is (100+100)m = 200m. So, (x+2x) * 8 = 200. Solving this equation, we get x = 10 m/s. Converting this to km/hr, the speed of the faster train is 10 * 18/5 = 36 km/hr.

    A man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is: 1. 8.5 km/hr 2. 9 km/hr 3. 10 km/hr 4. 12.5 km/hr

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 3
    Explanation
    The man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. To find the man's speed against the current, we need to subtract the speed of the current from the man's speed with the current. Therefore, the man's speed against the current is 15 km/hr - 2.5 km/hr = 12.5 km/hr.

      A bag contains 2 red, 3 green and 2 blue balls. Two balls are drawn at random. What is the probability that none of the balls drawn is blue? 1. 10 21 2. 11 21 3. 2 7 4. 5 7

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 1
    Explanation
    The probability of drawing a non-blue ball on the first draw is 5/7, since there are 5 non-blue balls out of a total of 7 balls. After drawing a non-blue ball on the first draw, there are 4 non-blue balls left out of 6 balls. Therefore, the probability of drawing a non-blue ball on the second draw is 4/6. The probability of both events happening is the product of their individual probabilities, so the overall probability is (5/7) * (4/6) = 20/42, which simplifies to 10/21.

    In a class, there are 15 boys and 10 girls. Three students are selected at random. The probability that 1 girl and 2 boys are selected, is: 1. 21 46 2. 25 117 3. 1 50 4. 3 25

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 1
    Explanation
    The probability of selecting 1 girl and 2 boys can be calculated by multiplying the probability of selecting 1 girl from 10 girls (10/25) with the probability of selecting 2 boys from 15 boys (15/25 * 14/24). Simplifying this expression gives us (10/25) * (15/25 * 14/24) = 21/46. Therefore, the correct answer is option 1.

    .  In how many ways can a group of 5 men and 2 women be made out of a total of 7 men and 3 women? 1 63 2. 90 3. 126 4. 45    

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 1
    Explanation
    In this question, we need to find the number of ways to select a group of 5 men and 2 women out of a total of 7 men and 3 women. This can be solved using combinations. The number of ways to select 5 men out of 7 is given by 7C5 = 7!/(5!*(7-5)!) = 7!/(5!*2!) = (7*6)/(2*1) = 21. Similarly, the number of ways to select 2 women out of 3 is given by 3C2 = 3!/(2!*(3-2)!) = 3!/(2!*1!) = 3. Therefore, the total number of ways to form the group is 21 * 3 = 63.

      The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is: 1. 15 2. 16 3. 18 4. 25

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 2
    Explanation
    The cost price of 20 articles is the same as the selling price of x articles. This means that the cost price and selling price per article are the same. If the profit is 25%, it means that the selling price is 125% of the cost price. Since the cost price and selling price per article are the same, we can set up the equation: 125% of the cost price = cost price. Simplifying this equation, we get: 1.25 * cost price = cost price. Dividing both sides by the cost price, we get: 1.25 = 1. Therefore, x = 16.

    A shopkeeper expects a gain of 22.5% on his cost price. If in a week, his sale was of Rs. 392, what was his profit? 1. Rs. 18.20 2. Rs. 70 3. Rs. 72 4. Rs. 88.25

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 3
    Explanation
    The shopkeeper expects a gain of 22.5% on his cost price. This means that he wants to make a profit of 22.5% of the cost price.

    Let's assume the cost price is x.

    So, the profit he wants to make is 22.5% of x, which is 0.225x.

    The selling price is the cost price plus the profit, which is x + 0.225x = 1.225x.

    We are given that the selling price is Rs. 392.

    So, 1.225x = 392.

    Dividing both sides by 1.225, we get x = 320.

    The profit is the selling price minus the cost price, which is 392 - 320 = Rs. 72.

    Therefore, the correct answer is option 3, Rs. 72.

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 1
    Explanation
    The ratio of increased seats can be found by multiplying the current ratio of seats by the respective increase percentages. The increased ratio for Mathematics would be 5 * 1.4 = 7, for Physics it would be 7 * 1.5 = 10.5 (rounded to 11), and for Biology it would be 8 * 1.75 = 14. The ratio of increased seats would therefore be 7 : 11 : 14, which simplifies to 2 : 3 : 4.

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    • Option 5

    Correct Answer
    A. Option 4
    Explanation
    The data provided in both statements I and II together are not sufficient to answer the question. Statement I only tells us that at least 2 faces of the rectangular block are squares, but it doesn't provide enough information to determine if the block is a cube. Statement II tells us the volume of the block is 64, but this also isn't enough information to determine if it is a cube. We would need additional information about the dimensions of the block to determine if it is a cube. Therefore, the correct answer is option 4.

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    • Option 5

    Correct Answer
    A. Option 2
    Explanation
    The difference between a two-digit number and the number obtained by interchanging the positions of its digits is 36. This means that the original number must be greater than the number obtained by interchanging its digits. Let's assume the original number is 10x + y, where x and y are the digits. The number obtained by interchanging the digits is 10y + x. The difference between these two numbers is (10x + y) - (10y + x) = 9x - 9y = 9(x - y). Since the difference is 36, we can conclude that x - y = 4. Therefore, the difference between the two digits is 4.

    A box contains 2 white balls, 3 black balls and 4 red balls. In how many ways can 3 balls be drawn from the box, if at least one black ball is to be included in the draw? 1. 32 2. 48 3. 64 4   None of these    

    • Option 1

    • Option 2

    • Option 3

    • Option 4

    Correct Answer
    A. Option 3
    Explanation
    There are a total of 9 balls in the box. To find the number of ways to draw 3 balls with at least one black ball, we can consider two cases:
    1) Drawing exactly one black ball and two other balls (white or red).
    There are 3 ways to choose the black ball and 6 ways to choose the other two balls (white or red). So, there are 3 * 6 = 18 ways for this case.
    2) Drawing two black balls and one other ball (white or red).
    There are 3 ways to choose the first black ball, 2 ways to choose the second black ball, and 6 ways to choose the other ball (white or red). So, there are 3 * 2 * 6 = 36 ways for this case.
    Adding the number of ways from both cases, we get 18 + 36 = 54 ways. However, we have counted the case where we draw all three black balls twice. So, we need to subtract 1 from the total. Therefore, the final answer is 54 - 1 = 53 ways.
