When B covers 960 m, C covers 936 m.
When B covers 1000 m, C covers
Races and Games
∴ B can give C a start of
(1000 - 975) = 25 m.

8) Three men A, B and C walk around a circle, 1760 meters in circumference, at the rates of 160 meters, 120 meters and 105 meters per minute respectively. If they all start together and walk in the same direction, when will they be first together again?

Races and Games
Again, to gain 55 meters over C, A takes 1 min.
∴To gain 1760 meters over C, A takes

Thus, A and B will be together after 44 minutes, while A, and C are together again after 32 minutes.

9) In a game of billiards, A can give B 12 points in a game of 60 points and A can give C 10 points in a game of 90 points. How many points can C give B in a game of 70?

73 points
63 points
80 points
None of these.

Answer: B

Explanation:

If A scores 60 points, B scores 48 points.
Also, if A scores 90 points, C scores 80 points.
A: B = 60:48 and A: C = 90:80
B: C = (A/C) * (B/A)
= (90/80) * (48 /60) = 9/10
When C scores 10 points B scores 9 points.
So, When C scores 70 points B scores = (9/10) * 70 = 63 points

10) In a 100 m race, A covers the distance in 36 seconds and B covers in 45 seconds. In this race, A beats B by

20 m
25 m
22.5 m
9 m

Answer: A

Explanation:

Speed of B = Distance / time
= 100 / 45 = 20 /9 m/s
Distance = speed * time
Distance covered by B in (45 - 36) = 9 seconds:
Races and Games
∴ A beats B by 20 meters.

Solution 2:

Distance covered by B in 45 seconds = 100 meters
Distance covered by B in 9 seconds = (100/45) * 9 = 20 meters
So, when A covers 100 meters in 36 seconds, B was 20 meters away from the winning post. Thus, A beats B by 20 meters.
