Explanatory Answer
Method of solving this CAT Quantitative Ability Question from TIme, Speed, Distance and Work question
(a) In a 200 m race, A beats S by 20 m and A beats N by 40 m
Then, when S runs 180m, N runs 160 m only
Hence, when S runs 100 m, N runs
160/180 × 100 = 88.88 m
∴ S beats N by 100 – 88.88 = 11.11 m
