The present age of Rakshak is twice the present age of Son-al. Five years hence, Sonal’s age will be twice the present , age of Arati. Five years ago, the ratio of the ages of Arati and Kiran was 2 : 3 respectively. Kiran’s present age is 20 years. Find Rakshak’s present age.
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
