The speed of three cars is in the ratio of 2 : 3 : 4 . The ratio of the times taken by these cars to travel the same distance is -

A 2 : 3 : 4

B 4 : 3 : 6

C 4 : 3 : 2

D 6 : 4 : 3

Solution

Correct Answer: Option D

দেওয়া আছে,
car তিনটির গতির অনুপাত = 2 : 3 : 4

∴ অতিক্রান্ত দূরত্বের অনুপাত = 1/2 : 1/3 : 1/4
= (1/2 x 12) : (1/3 x 12) : (1/4 x 12)
= 6 : 4 : 3
