In a race of 350 m, A can beat B by 50 m and C by 25 m. In a race of 650 m, C will beat B by:

OPtion

1) 80.0
2) 25.0
3) 50.0
4) 85.0
5) 60.0
6) 82.5
7) 50.5
8) 87.5
9) 75.0
10) None of these

Solution

When A covers 350m B Covers 300m
When A Covers 350m C covers 225m

A : B = 350 : 300
A : C = 350 : 325

C/B = (C/A*A/B) = (325/300) = 325:300
When C covers 325 m, B covers 300 m.
When C covers 650 m, B covers (300/325)*650)m = 600
Therefore, C beats B by (650 - 600) m = 50 m.

Option 3)

Correct Option: 3 Best Solution (1)

Devendra Marghade   4 years AGO

When A=350 m, B=300 m, C=325 m.
Ratio of distance covered=350 : 300 : 325=14 : 12 : 13
When, C=650, B=(12/13)*650=600 m.
So, in a race of 650 m, C beat B by 50 m.
