Correct Answer: 1542/3 s
Explanation:
According to the formula,
Time taken by the winner/Distance covered by the loser = Difference of winning time/ Difference of winning distance
? Time taken by P//(1000 - 72) = 12/72
? Time taken by P = (12/72) x 928
= 464/3 = 1542/3 s
Correct Answer: 30 m
Explanation:
To reach the winning post, A has to cover (250 - 140)m = 110 m
From the the ratio of 1 : 2 ,
When A covers 1m, then B covers 2 m.
When A covers 110 m, then B covers
( 2 x 110)m = 220 m
? A wins by (250 - 220) = 30 m
Correct Answer: 70 m
Explanation:
A is 13/4 faster than B.
Then, ratio of the rates of A and B = 7 : 4
3 m are gained in a race of 7 m .
30 m are gained in a race of (7/3) x 30 = 70 m
Correct Answer: 39 m
Explanation:
If A runs 600 m, then B runs 570 m.
If A runs 400 m, B then runs (570/600) x 400 m = 380 m
When B runs 500 m, then C runs 475 m,
When B runs 380 m, then C runs (475/500) x 380 = 361 m
? A beats C by (400 - 361) = 39 m
Correct Answer: 5
Explanation:
In a game of 50.
While A scores 50, B scores 50 - 6 = 44 and in a game of 65. While A scores 65, C scores 65 - 13 = 52.
? While A scores 50, C scores 52 / 65 × 50 = 40.
? While B scores 44, C's score = 40.
While B scores 55, C's score = 40 / 44 × 55 = 50.
? In a game of 55,
B can give C 55 - 50 = 5 points.
Correct Answer: 1662/3 m
Explanation:
Time taken by L to run 1 km = 600 s
Time taken by M to run 1 km = 720 s
? L can give M a start of (720 - 600) = 120 s
? In 720 s, M runs 1000 m.
In 120 s M runs = (1000/720) x 120 = 500/3 m = 1662/3 m
Hence, L can give a start of 1662/3 m
Correct Answer: 50 m
Explanation:
Clearly, Yogesh beats vijay by 20 s.
Distance covered by vijay in 400 s = 1000 m
[? 6 min 40 s = 400 s]
Distance covered by Vijay in 20 s = (1000/400) x 20 m = 50 m
? Yogesh beats Vijay by 50 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: 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: 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
