Q.
In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by:
A.
22.75 m
B.
25 m
C.
19.5 m
D.
18.5 m
View Answer
Correct choice: B
Explanation:
A : B = 200 : 169. A : C = 200 : 182. C/B = (C/A*A/B) = (182/200*200/169) = 182:169 When C covers 182 m, B covers 169 m. When C covers 350 m, B covers (169/180*350)m = 325 m Therefore, C beats B by (350 - 325) m = 25 m.
