Text ExplanationVideo Explanation
Let's take Rajesh and Garima's ages to be R and G, respectively
From the given ratio, we can see that Rajesh is older than Garima, so let's take R=G+x
When Rajesh was of age G, which was x years ago, Garima was of G-x years old
Giving the ratio as
This gives us G as 3x, which in turn gives R as 4x
We are asked the ratio when Gramia becomes 4x years old.
By that time, Rajesh will be 5x years old.
Giinv their ratio as
Therefore, Option D is the correct answer.
