The ratio of the speed of Aman, Kamal and Manan is 2 : 3 : 4 respectively. What is the ratio of the time taken by Aman, Kamal and Manan respectively to cover the same distance?
Answer & explanation
Correct answer: option 3
The ratio of time ∝ $\frac{1}{speed}$ when distance is same
Aman : Kamal : Manan
Speed 2 : 3 : 4
Time $\frac{1}{2}$ : $\frac{1}{3}$ : $\frac{1}{4}$ (the inverse of a ratio)
6 : 4 : 3
