Question: In a race of 200 meters, B can give a start of 10 meters to A, and C can give a start of 20 meters to B. The starts that C can give to A, in the same race is -

Solution:
According to the question,
When B runs 200 m meters, A runs 190 meters;
Hence, when B runs 180 meters,
A runs = (190×180)/200
= 171 meters

When C runs 200m, B runs 180 meters.
Hence,
C will give a start to A by = 200 - 171
= 29 meters
