Answer 2

"Answer: Ration of their present age = 2 : 3

Given is the ratio of two friends

Ration: $4\quad :\quad 9\quad \Rightarrow \quad 4x\quad =\quad 9x$

Solution:

Younger ones age $=\quad 4x\quad \times \quad 1.5\quad =\quad 6x$

Ratio of their "ages":

$\Rightarrow 6x = 9x$

On dividing by 3, we get

$\Rightarrow 2 : 3$

Then we get the "ratio" of their present age as 2:3"
