Question 1

Walking at‌35of his usual speed, a man covers a certain distance in one hour and 40 minutes more than the time he takes to cover the distance at his usual speed. The time taken by him to cover the same distance at is usual speed is:

Accepted Answer

Let usual speed be S and time be T. New speed is (3/5)S, so new time is (5/3)T. The difference (5/3)T - T = (2/3)T = 1 hour 40 minutes = 100 minutes. So, T = 150 minutes = 2.5 hours or 5/2 hours.

Question 2

The speed of a boat in still water is 30 km/h and the rate of the current is 6 km/h. The distance (in km) travelled upstream in 5 minutes is:

Accepted Answer

Upstream speed = Boat speed - Current speed = 30 - 6 = 24 km/h. Convert 5 minutes to hours (5/60 = 1/12 h). Distance = Speed × Time = 24 × (1/12) = 2 km.

Question 3

The average weight of 6 persons increases by 2.5 kg when a new person comes in place of one of them weighing 55 kg. What might be the weight (in kg) of the new person?

Accepted Answer

The total weight increases by 6 persons * 2.5 kg/person = 15 kg. The new person's weight is the old person's weight plus this increase: 55 kg + 15 kg = 70 kg.

Question 4

The value of 21 × [(9 - 4) ÷ {(8 ÷ 8 of 4) + (4 ÷ 4 of 2)}] is:

Accepted Answer

Apply BODMAS: first 'of', then division, then addition inside brackets. (8 of 4 = 32, 4 of 2 = 8). Then perform divisions, addition, subtraction, and finally multiplication to get 140.

Question 5

What is the value of x, if [0.9 {1.1 - 0.3(0.3 - 0.2 ÷ 0.5) + 0.4}] ÷ 0.81 = x+1 ?

Accepted Answer

Follow BODMAS: first division (0.2 ÷ 0.5 = 0.4), then subtraction (0.3 - 0.4 = -0.1), then multiplication (0.3 * -0.1 = -0.03). Simplify inside brackets, then multiply by 0.9, and finally divide by 0.81 to find x+1. Solve for x.

Question 6

If the difference of the mode and median of a data is 38, then the difference of the median and mean is:

Accepted Answer

Use the empirical relation: Mode = 3 Median - 2 Mean. Given Mode - Median = 38. Substitute and simplify to find Median - Mean = 19.

Question 7

The diameter of the base of a solid right circular cone is 22 cm and its height is 60 cm. The cost of polishing its curved surface at Rs. 1.40 per cm2is: (Take π =‌227)

Accepted Answer

First, calculate the slant height (l) using Pythagoras theorem: l = sqrt(r^2 + h^2). Then, find the curved surface area (CSA) using πrl. Finally, multiply CSA by the cost per cm² to get the total cost.

Question 8
