1.	In a race of 200 metres, B can give a start of 10 metres to A and C can give a start of 20 metres to B. What is the start that C can give to A in the same race?
Answer» Ratio of the distances covered by A and B = 190 : 200 = 1710 : 1800 Ratio of the distances covered by B and C = 180 : 200 = 1800 : 2000 ⇒ Ratio of the distances covered by A and C = 1710 : 2000 = 171 : 200 Hence C will give a start of (200 m – 171 m) = 29 m to A in the same race.

In a race of 200 metres, B can give a start of 10 metres to A and C can give a start of 20 metres to B. What is the start that C can give to A in the same race?

Answer»

Ratio of the distances covered by A and B = 190 : 200 = 1710 : 1800

Ratio of the distances covered by B and C = 180 : 200 = 1800 : 2000

⇒ Ratio of the distances covered by A and C = 1710 : 2000 = 171 : 200

Hence C will give a start of (200 m – 171 m) = 29 m to A in the same race.
