Marks: +1, -0

Nine years later, age of B will be equal to the present age of A.

Solution:

B’s present age = x years
C's present age =

x/2

years
and A’s present age = (x + 9) years
According to the question,
(x + 9 + 3) + (x - 4 ) = 76
⇒ 2x + 8 = 76
⇒ 2x = 68 ∴ x = 34
Hence, C’s age after 10 years

=x/2+10=34/2+10

= 17 +10 = 27 years
