Question 10

Present age of A is 2 times the present age of B. After 8 years the B's age will be 4 times of C's present age. If C celebrated his fifth birthday 9 years
ago, then what is the present age (in years) of A?

Solution

C celebrated his fifth birthday 9 years ago, => C's present age = $$9 + 5 = 14$$ years

Also, after 8 years the B's age will be 4 times of C's present age,

=> B's present age = $$(4\times14)-8=56-8=48$$ years

Thus, A's age = $$2\times48=96$$ years

=> Ans - (B)
