A) 3 : 2
B) 5 : 2
C) 9 : 4
D) 9 : 13
Correct Answer: A
Solution :
If two persons start at the same time from two points A and B towards each other and after crossing they take a and b hours in reaching B and A respectively, then \[\frac{\text{A }\!\!'\!\!\text{ s}\,\,\text{speed}}{\text{B }\!\!'\!\!\text{ s}\,\,\text{speed}}=\frac{\sqrt{b}}{\sqrt{a}}=\frac{\sqrt{9}}{\sqrt{4}}=\frac{3}{2}\]You need to login to perform this action.
