Races and Games Practice Test 1 with solutions

Question : 20 of 40

Marks: +1, -0

Two men A and B run a 500 m race, A having 140m start, their speeds are as 3 : 4. Then, A wins by:

10 m
20 m
40 m
60 m

Solution:

Here, A will have to cover a distance of (500 – 140) = 360 m to reach the winning point while B 500 m
Now, A covers 3 m while B covers 4 m
∴ A covers 360 m while B covers

4/3 × 360

= 480 m
Hence, B will be (500 – 480) = 20 m behind the winning post.
∴ A wins by 20 m.
