Question

monu's father is 26 years younger than monu's grand father and 29years older than manu. The sum of the ages of all the three in 135years. what is the age of each one of them

Answer 1

Let the age of monu be a
Monu's father's age = a+29
Monu's grandfather's age = a+29+26 = a+55

a+a+29+a+55 = 135
=> 3a = 135 - 84
=> 3a = 51
=> a = 17

Monu's age = 17 years
Monu's father's age = 46 years
Monu's grandfather's age = 72 years

Answer 2

 Let the age of monu be a, his father be b and his grandfather be c

b = c-26
c = b+26

b = a+29
a = b-29

a + b + c = 135
b-29+b+b+26 = 135
3b-3 = 135
3b = 138
b = 46 

Monu is 46
His father is 75
His grandfather is 101
