Let Baichung�s father's present age be x years
Given Baichung�s father is 29 years older than Baichung
Hence Baichung�s age is (x − 29) years
Baichung�s grandfather is 26 years older than Baichung�s father.
Hence Baichung�s grandfather�s age = (x + 26) years
Given sum of three ages = 135 years
∴ x + (x − 29) +(x + 26) = 135
3x − 3 = 135
3x = 135 + 3 = 138
∴ x = 46
Baichung�s father�s age = 46 years
Baichung�s grandfather�s age = (x + 26) = (46 + 26) = 72 years
Baichung's age = (x − 29) = (46 − 29) = 17 years
