Question

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?

Options

• 11.11 m

• 10 m

• 12 m

• 25 m

Answer 1

11.11 m

Explanation:

When A runs 200 m
          S runs 180 m
          N runs 160 m

When S runs 100 m. N will run`=100xx160/180=88.89`

i.e. S will beat N by (100 − 88.89) = 11.11 m
