Answers & Solutions:

1) Answer (D)

2) Answer (D)

3) Answer (B)

4) Answer (C)

5) Answer: 360

Let the distance between the 2 cities be ‘x’ km.
By the time the bike starts, the car has already traveled for an hour (60 km).
Distance between the car and the bike when the bike starts = (x-60) km.

Time taken by the car and bike to meet each other after the bike starts = (x-60)/(40+60) = (x-60)/100 hours.

The car takes 4 hours less to reach city B than the time taken by the bike to reach city A.
Let ‘t’ be the time taken by the car to reach city B after crossing the bike.
=> t*60 = (x-60)/100 * 40
t = (x-60)/150  ———(1)
Time taken by the bike after crossing the car to reach city A = t+4 hours.

(t +4)*40 = (x-60)/100*60 + 60
t+4 = 1.5(x+40)/100
t+4 = (1.5x + 60)/100
t = (1.5x-340)/100 ————(2)

Equating (1) and (2), we get,
(x-60)/150 = (1.5x-340)/100
2x – 120 = 4.5x – 1020
2.5x = 900
x = 360 km

6) Answer (B)

The horse will keep running at the speed of 15 kmph until Raman and Rajeev meet.

Let us assume the distance between their houses is $x$ km.

Since both are moving towards each other,

their relative speed = (6 + 4) kmph = 10 kmph

So, time required to meet = $\dfrac{x}{10}$ hr

Distance covered by the horse = $3k$ km

Time taken by the horse = $\dfrac{3k}{15}$ hr

Both the times must be equal.

So, $\dfrac{x}{10}$ = $\dfrac{3k}{15}$

On solving, we get

$x = 2k$

Hence, option B is the correct answer.

7) Answer (D)

8) Answer (A)

9) Answer (A)

10) Answer (B)

Given that the train travels first 200 km at 160 km/hr
Time taken = $\dfrac{200}{160} = \dfrac{5}{4}$ hours
Train travels remaining 200 km at 120 km/hr
Time taken = $\dfrac{200}{120} = \dfrac{5}{3}$ hours
Total time taken = $\dfrac{5}{4} + \dfrac{5}{3} = \dfrac{15 + 20}{12} = \dfrac{35}{12} \times 60 = 175$ minutes

11) Answer (A)

Ratio of the speed of A and B = 3:4$\pi$. This implies that for every 3m traveled by A , B will travel 4$\pi$m.

Radius of the Circle =2m

Circumference of the circle =4$\pi$m.

Hence for one complete round of B, A will travel 3m.

A cannot meet B at a diametrically opposite point because for every meter A moves B covers a one-third of a circle.

Thus they will meet at the same point.

For A to reach back at the starting point it will travel 8m.

Thus for both the players to reach at the same point it has to be a multiple of 3 and 8 which is 24.

Hence the answer is Option A.

12) Answer (B)

Speed of Raj = 51 km/hr
Time taken by Raj to travel a certain distance = $2\dfrac{1}{3} = \dfrac{7}{3}$ hours
Hence, Distance travelled by Raj = $\dfrac{7}{3} \times 51 = 119 km$
Given, Speed of Kiran = 68 km/hr
Time required for Kiran to travel 119 km at 68 km/hr = $\dfrac{119}{68} = \dfrac{7}{4} = 1\dfrac{3}{4}$ hours

13) Answer (B)

14) Answer (B)

Let the distance between any two consecutive trees = $d$ metres

=> Total distance between the 37 trees = $36d$ metres

Time taken to reach the 13th tree = 20 seconds

=> Speed of car = distance/time

= $\frac{12d}{20}=\frac{3d}{5}$ m/s

Thus, time taken to reach the last tree from the first tree = $\frac{36d}{\frac{3d}{5}}$

= $36\times\frac{5}{3}=60$ seconds

$\therefore$ The car will take (60-20) = 40 seconds more to reach the last tree

=> Ans – (B)
