Dear Student

Let the age of Baichung’s father be x.
Then, the age of Baichung’s grandfather = (x+26)
and, Age of Baichung = (x-29) According to the question, x + (x+26) + (x-29) = 135
⇒3x+26-29=135
⇒3x-3=135
⇒3x=135+3
⇒3x=138
⇒x=138/3
⇒x=46
Age of Baichung’s father = x = 46
Age of Baichung’s grandfather = (x+26) = 46 + 26 = 72
Age of Baichung=(x-29)=46-29=17

Thanks
