Answer:B
A can defeat B by 31 metres and C by 18 metres in a 200-meter race. In a 350-meter race, C will win by:
A. 22.75 m B. 25 m C. 19.5 m D. 7 4/7m
Explanation: The ratio of A to B is 200 to 169.The ratio of A to C is 200 to 182.182 /200x200/169 = 182 : 169 C/B = C/A x A/B,When C runs 182 metres, B runs 169 metres.B covers 169/182 x 350 m = 325 m when C covers 350 m.182.As a result, C wins by (350 - 325) m = 25 m.
