Four years ago, the average age of A and B was 18 years. At present the average age of A, B, and C is 24 years. What would be the age of C after 8 years?
Note
∴ Some of the present ages of A and B
= (18 × 2) + (4 × 2)
= (36 + 8) years
= 44 years.
∴ Some of the present ages of A, B, and C
= (24 × 3) years
= 72 years.
∴ C's present age = (72 - 44) years
= 28 years.
∴ C’s age after 8 years = (28 + 8) years
= 36 years.
