When Rajesh's age was same as the present age of Garima, the ratio of their ages was 3 : 2. When Garima's age becomes the same as the present age of Rajesh, the ratio of the ages of Rajesh and Garima will become
A
5 : 4
B
2 : 1
C
4 : 3
D
3 : 2
Answer
5 : 4
Explanation
Solution
Let's denote Rajesh's present age as R and Garima's present age as G.
Given, when Rajesh's age was G, the ratio of their ages was 3:2. So, we can write:
GR−G=23
We need to find the ratio when Garima's age becomes R. So, the ratio will be: G+(R−G)R=RR=1
Therefore, the ratio of their ages will be 1:5.
