Question

Rohans father is 26 yrs elder to rohan.the father is 20 yrs younger to rohans grandfather.if sum of the 3 is 84 then what is the age of rohans father?

Answer 1

26+20+x=84
x=84-20-26
x=32

Answer 2

let rohan's age be x

rohan's father's age = x + 26

rohan's grandfather's age = x +26 +20

now

according to the question

⇒ (x) + (x + 26) + (x + 26 + 20) = 84

⇒ 3x + 26 + 26 + 24 = 84

⇒ 3x + 72 = 84

⇒ 3x = 84 - 72

⇒ 3x = 12

⇒ x = 12 ÷3

⇒ x = 4

∴ rohan's age = 4

now

⇒ rohan's father's age = x +26

= 4+26

= 30 years
