TO FIND The age of the eldest son.

SOLUTION:

As we are given in the question,

The sum of two ages of the elder son & one son is 15.

Also,

Eldest son's age=11

then,

11-2=9(elder son)

9-3=6(youngest son)

It satisfies the statement "the sum of two ages of the elder son & one son is 15."(9+6=15)

Therefore,

The age of the eldest son is 11 years.
