Options- A. 222 m
- B. 220 m
- C. 167 m
- D. 176 m
- Correct Answer
- 176 m
Explanation? B runs 1000 m while C 960 m
? B runs 995 m while C 960 * 995 / 1000 = 912 m
Now, A runs 1000 m while C 960 m
? A runs 2000 m while C 2000 * 912 / 1000 = 1824 m
Hence, A can give C (2000 ? 1824) = 176 m start. - 1. A can run 440 m in 51 seconds and B in 55 seconds. By how many seconds will B win if he has 40 m start?

Correct Answer: 1 seconds
Explanation:
To reach the winning post B will have to cover the distance (440 ? 40) = 400 m.
Hence,
time taken by B to cover 440 meter = 55
time taken by B to cover 1 meter = 55 / 440
time taken by B to cover 400 meter = 400 x 55 / 440 = 40 x 55/44 =10 x 55/11 = 10 x 5
time taken by B to cover 400 meter = 50 Sec.
Since, A reaches the winning post in 51 sec. while B in 50 sec.
So, B will win by 1 second.
Correct Answer: 10 m
Explanation:
Distance covered by B in 27 seconds = 100 x 27 / 30 = 90 m
Hence, A will beat B by (100 ? 90) = 10 m.
Correct Answer: 20 points
Explanation:
A : B = 200 : 160
A : C = 200 : 144
? B/C = (B/A) x (A/C) = (160/200) x (200/144)
= 160/144 = 10/9 = 200/180
Hence, B can give C 20 points
Correct Answer: 56 m
Explanation:
According to the question, A : B = 200 : 150
and B : C = 200 : 192
? A : C = (A/B) x (B/C) = (200/150) x (200/192) = 200/144
So, A beats C by (200 - 177) = 56 m
Correct Answer: 8
Explanation:
A : B = 160 : 150, A : C =160 : 130
B/C = (B/A) x (A/C) = (150/160) x (160/130) = 15/13 = 60 : 52
? In a game of 60, B can give C = (60 - 52)= 8 points
Correct Answer: 3 min.
Explanation:
If A runs 880 meter then B runs 840 meters and C runs 798 meters.
? B runs 840 m while C 798 m
? B runs 880 m while C 798 * 880 / 840 = 836 m
Now, 880 ? 836 = 44 m
Hence, C runs 44 m in 9 seconds
? C runs 880 m in 9 * 880 / 44 = 180 sec. = 3 min.
Correct Answer: 50
Explanation:
Let assume the game has P points.
Then A has P points , B has (P ? 15) and C has (P ? 22) points and also if B has P points then C has (P ? 10) points.
Applying chain rule,
P x P ( P ? 22 ) = P ( P ? 15) ( P ? 10)
? P2 ? 22P = P2 ? 25P + 150
? 3P = 150
? P = 50
Correct Answer: 8
Explanation:
? B scores 75 points while A 80
? B scores 60 points while A = 80 x 60 / 75 = 64
Again, A scores 80 points while C = 65
? A scores 64 points while C = 65 x 64 / 80 = 52 points
Hence, in a game of 60, B can give C (60 ? 52) = 8 points
Correct Answer: 20 m
Explanation:
Here, A will have to cover a distance of (500 ? 140) = 360 meters to reach the winning point while B 500 meters . A covers 3 while B covers 4.
? A covers 360 m while B covers 4 x 360/ 3 = 480 m
Hence, B will be (500 ? 480) = 20 m behind the winning post.
? A wins by 20 m.
Correct Answer: 324 m
Explanation:
Clearly, if A runs 600 meters, B runs = 540 m.
? If A runs 400 m, B runs = 540 x 400 / 600 = 540 x 4 / 6 = 90 x 4 = 360 m
Again, when B runs 500 m, C runs = 450 m
? When B runs 360 m, C runs = 450 x 360 / 500 = 45 x 36 / 5 = 9 x 36 = 324 m.
? A beats C by 400 - 324 = 76 m.
