A can beat B by 62 meters and C by 36 meters in a race of 400 meters. In a race of 700 meters C will beat B by:
Explanation:
Ratio of rates of A, B and C = 400 : (400 – 62) : (400-36) = 400 : 338 : 364 = 200 : 169 : 182.
i.e., C gains 13 meters in a race of 182 meters.
∴ In a race of 700 meters C will gain (13/182 × 700) = 50 meters.
Hence, option (b).
