CAT 1995 — QA Question 18
Linear RaceEasy
In a race of 200 m run, A beats S by 20 m and N by 40 m. If S and N are running a race of 100 m with exactly same speed as before, then by how many metres will S beat N?
Answer & solution
Correct answer: 11.11 m
11.11 m
- B
10 m
- C
12 m
- D
25 m
Solution
In the same time as A runs 200 m in the race, S runs 180 m and N runs 160 m.
In other words, in the same time as S runs 180 m, N runs 160 m.
So in the same time as S runs 100 m, N will run = 88.89 m.
Hence, in a 100 m race, S will beat N by (100 – 88.89) = 11.11 m.
