Answer: Option B
Explanation:
A : B = 200 : 169.
A : C = 200 : 182.
C | = | C | x | A | = | 182 | x | 200 | = 182 : 169. | ||||
B | A | B | 200 | 169 |
When C covers 182 m, B covers 169 m.
When C covers 350 m, B covers | 169 | x 350 | m | = 325 m. | |
182 |
Therefore, C beats B by (350 – 325) m = 25 m.
