The present age of B is more than twice A’s present age by 4 years. The ratio of A’s age 6 years hence to B’s age 2 years hence will be 4:7. What is C’s present age if C is 2 years older than B? ((in years)

Let the present age of A be x then, present age of B = 2x + 4 Now, according to the question (x + 6)/(2x + 4 + 2) = 4/7 7x + 42 = 8x + 24 x = 18 Hence, present age of C = 2x + 4 + 2 = 36 + 6 = 42 years
