Let Hamad's father's present age be x years
Given Hamad'�s father is 26 years older than Baichung
Hence Hamad's age is (x − 26) years
Hamad's grandfather is 26 years older than Hamad'�s father.
Hence Hamad's grandfather�s age = (x + 26) years
Given sum of three ages = 135 years
∴ x + (x − 26) +(x + 26) = 135
3x = 135
∴ x = 45
Hamad's father�s age = 45 years
Hamad'�s grandfather�s age = (x + 26) = (45 + 26) = 71 years
Hamad's age = (x − 26) = (45 − 26) = 19 years
