a) 48 : 35
b) 28 : 15
c) 24 : 20
d) 20 : 21
Answer: d
Explanation:
7 jumps of Tom = 5 jumps of Jerry
$$\frac{{{\text{Tom}}}}{{{\text{Jerry}}}} = \frac{5}{7}$$
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
