Solution
Let Arati's age 5 years ago = $2x$
and Kiran's age 5 years ago = $3x$
=> Kiran's present age = $(3x + 5) = 20$ [Given]
=> $x = \frac{15}{3} = 5$
=> Arati's present age = $2x + 5$
= 2*5 + 5 = 15 years
Now, after 5 years Sonal’s age will be twice the present age of Arati
=> Sonal's age after 5 years = 2*15 = 30 years
and Sonal's present age = 30 - 5 = 25 years
$\therefore$ Rakshak's present age = 2*25 = 50 years
