3) 14. M is 30% of Q, Q is 20% of P and N is 50% of P. What is M / N

3/25

2/25

5/25

6/24

To find M/N, we need to determine the relationship between M and N. Since M is 30% of Q and Q is 20% of P, we can say that M is (30/100) * (20/100) = 6/100 of P. Similarly, N is 50% of P, which is 50/100 = 1/2 of P. Therefore, M/N is (6/100) / (1/2) = (6/100) * (2/1) = 12/100 = 3/25.

6) In a city 100% votes are registered, in which 60% vote for congress and 40% vote for BJP. There is a person A, who gets 75% of congress votes and 8% of BJP votes. How many votes got by A?

48%

49.2%

48.2%

50%

None of the above

Person A gets 75% of the votes for Congress, which is 60% of the total votes. Therefore, A gets 0.75 * 0.60 = 0.45 or 45% of the total votes for Congress. Similarly, A gets 8% of the votes for BJP, which is 40% of the total votes. Therefore, A gets 0.08 * 0.40 = 0.032 or 3.2% of the total votes for BJP. Adding both percentages, A gets a total of 45% + 3.2% = 48.2% of the total votes.

7) Raj drives slowly along the perimeter of a rectangular park at 24 kmph and completes one full round in 4 min. If the ratio of length to bredth of the park is 3 : 2, what are the dimansions?

450 m x 300 m

150 m x 100 m

480 m x 320 m

100 m x 100 m

The time taken to complete one full round is 4 minutes. Since the speed is given in kmph, we need to convert it to m/s. 24 kmph is equal to 24000 m/60 min = 400 m/min = 400/60 m/s = 6.67 m/s. The distance covered in one full round is the perimeter of the rectangular park. Let the length of the park be 3x and the breadth be 2x. The perimeter is given by 2(3x + 2x) = 10x. We know that distance = speed x time. So, 10x = 6.67 x 4 x 60. Solving this equation, we get x = 32. Therefore, the length is 3x = 3 x 32 = 96 and the breadth is 2x = 2 x 32 = 64. So, the dimensions of the park are 96 m x 64 m.

9) 1. A cow and horse are bought for Rs.2,00,000. The cow is sold at a profit of 20% and the horse is sold a t a loss of 10%. The overall gain is Rs.4000, the Cost price of cow?

130000

80000

70000

120000

The overall gain of Rs. 4000 is the difference between the profit made on selling the cow and the loss incurred on selling the horse. Let's assume the cost price of the cow is C. The profit made on selling the cow would be 20% of C, which is 0.2C. The loss incurred on selling the horse would be 10% of 2,00,000 - C, which is 0.1(2,00,000 - C). Therefore, the equation becomes 0.2C - 0.1(2,00,000 - C) = 4000. Solving this equation, we find C = 80,000.

Explanation

The overall gain of Rs. 4000 is the difference between the profit made on selling the cow and the loss incurred on selling the horse. Let's assume the cost price of the cow is C. The profit made on selling the cow would be 20% of C, which is 0.2C. The loss incurred on selling the horse would be 10% of 2,00,000 - C, which is 0.1(2,00,000 - C). Therefore, the equation becomes 0.2C - 0.1(2,00,000 - C) = 4000. Solving this equation, we find C = 80,000.

None of the above

The child first goes 90m in the east, then turns right and goes 20m. From this point, he turns right again and goes 30m to his uncle's place. Since his father is not there, he then goes 100m north and meets his father in a street. The distance between the starting point and the meeting point is the sum of the distances traveled in the east and north directions, which is 90m + 100m = 190m. Therefore, the correct answer is None of the above.

The mean of the three numbers is 10 more than the least of the numbers. Since the median is 5, the least number must be less than 5. Therefore, the least number is 30. The sum of the three numbers is 30 + 5 + 35 = 70.

12) At 12.00 hours, J starts to walk from his house at 6 kmph. At 13.30, P follows him from J's house on his bicycle at 8 kmph. When will J be 3 km behind P?

19.20 Hours

18.25 Hours

19.30 Hours

20 Hours

None of the above

J starts walking at 12.00 hours and P starts following him on his bicycle at 13.30 hours. The time difference between J and P is 1.5 hours. In this 1.5 hours, J walks a distance of 6 kmph * 1.5 hours = 9 km. Since P is on a bicycle and travels at a faster speed of 8 kmph, he covers a distance of 8 kmph * 1.5 hours = 12 km. Therefore, J will be 3 km behind P when P has covered a total distance of 9 km + 3 km = 12 km. This will happen in 12 km / 8 kmph = 1.5 hours. Adding this time to P's starting time of 13.30 hours, J will be 3 km behind P at 13.30 hours + 1.5 hours = 15.00 hours. Therefore, the correct answer is 19.30 hours.

Explanation

J starts walking at 12.00 hours and P starts following him on his bicycle at 13.30 hours. The time difference between J and P is 1.5 hours. In this 1.5 hours, J walks a distance of 6 kmph * 1.5 hours = 9 km. Since P is on a bicycle and travels at a faster speed of 8 kmph, he covers a distance of 8 kmph * 1.5 hours = 12 km. Therefore, J will be 3 km behind P when P has covered a total distance of 9 km + 3 km = 12 km. This will happen in 12 km / 8 kmph = 1.5 hours. Adding this time to P's starting time of 13.30 hours, J will be 3 km behind P at 13.30 hours + 1.5 hours = 15.00 hours. Therefore, the correct answer is 19.30 hours.

Let the present age of B be x. According to the given information, A is now 9 years older than B, so the present age of A is (x + 9). In 10 years, A will be (x + 9 + 10) = (x + 19) years old. B was 10 years ago, so B's age 10 years ago was (x - 10). According to the given information, in 10 years, A will be twice as old as B was 10 years ago, so we can write the equation (x + 19) = 2(x - 10). Solving this equation gives x = 39, which is the present age of B. Therefore, the correct answer is 39.

Explanation

Let the present age of B be x. According to the given information, A is now 9 years older than B, so the present age of A is (x + 9). In 10 years, A will be (x + 9 + 10) = (x + 19) years old. B was 10 years ago, so B's age 10 years ago was (x - 10). According to the given information, in 10 years, A will be twice as old as B was 10 years ago, so we can write the equation (x + 19) = 2(x - 10). Solving this equation gives x = 39, which is the present age of B. Therefore, the correct answer is 39.
