Tom is chasing Jerry. In the same interval of time Tom jumps 8 times while Jerry jumps 6 times. But the distance covered by Tom in 7 Jumps is equal to the distance covered by Jerry in 5 Jumps. The ratio of speed of Tom and Jerry is:

A. 48 : 35

B. 28 : 15

C. 24 : 20

D. 20 : 21

Answer: Option D

Solution(By Examveda Team)

Given;
7 jumps of Tom = 5 jumps of Jerry
Or, $$\frac{{{\text{Tom}}}}{{{\text{Jerry}}}} = \frac{5}{7}$$
Let Jerry's 1 leap = 7 meter and Tom's 1 leap = 5 meter
Then, ratio of speed of Tom and Jerry
= $$\frac{{8 \times 5}}{{6 \times 7}}$$
= $$\frac{{40}}{{42}}$$
= 20 : 21
