Question

Baichung's father is 26 year younger than Baichung's grandfather and 29 year older than Baichung. The sum of the ages of all three is 135 years. What is the age of each one of them?

Answer 1

Let Baichung's Age be = X
His father's = Y
His grand father's = Z
Given:-
Y = Z-26,
Z = Y+26
Y = X+29,
X= Y-29

And X+Y+Z =135
Putting ask the above values in to this equation:
Y-29+Y+Y+26 = 135
3Y-3= 135
3Y = 138
Y = 46

That means X =46-29= 17
And Z = 46+26 = 72
