Marks: +1, -0

In a race of 1 km, A can beat B by 40 m and B can beat C by 50 m. With how much distance can A beat C in a 0.5 km race?

Solution:

In 1 km race.
If A covers = 1 km = 1000 m
Then, B covers = 960 m
and C covers = 910 m
Difference between A and C
=

1000- 910= 90 m

In 1 km = 1000 m race A defeats C by

90/100m

∴ In 500 m race A defeats C by

{90/1000}×500=45m
