Question

Rohan's father is 5 years older than twice the rohan's age. His mother's age is the sum of his age and one third of his father's age. His sister is 2 years younger to him. The sum of their ages is 118 years. what are their ages ?

Answer 1

Step-by-step explanation:

Assume Rohan's age is x.

Then his father's age is 2x + 5

Then his mother's age is x + ⅓(2x + 5)

Then his sister's age is x - 2

The sum of their ages is 118 years.

x + 2x + 5 + x + ⅓ (2x + 5) + x - 2 = 118

⅓(17x + 14) = 118

17x + 14 = 354

17x = 340

x = 20

So Rohan's age is 20

Then his father's age is 45

Then his mother's age is 35

Then his sister's age is 18
