A. 10 min

B. 20 min

C. 24 min

D. 25 min

Answer: Option B

Solution(By Examveda Team)

Their relative speed in same direction
= (90 - 75) kmph
= 15 kmph
Time taken by jeep to catch car :
$$\eqalign{ & = \frac{5}{15} {\text{ hour}} \cr & = \frac{1}{3} {\text{ hour}} \cr & = \frac{1}{3} \times 60 {\text{ min}} \cr & = 20 {\text{ min}} \cr}$$
