Answer 1

Answer:

Rohan age 19

Mohan age 16

Step-by-step explanation:

Let the age of rohan be x

Father's age 2x

Sisters age 2x-30

Mohan age 4x-60

Now

x-3=4x-60

x=19

Rohan age 19

Mohan age 16

Answer 2

Answer:

Mohan's age = 16 years

Rohan's age = 19 years

Step-by-step explanation:

Let the age of Rohan = x years = y+3 years

Let the age of Rohan's father = 2(x) years

Let the age of Mohan = y years

Let the age of  Mohan's sister = (y/2) years

According to the question:-

2(x)-y/2=30 = 30

2(y+3)-y/2=30

2y+6-y/2 = 30

4y/2-y/2 = 24

3y/2 = 24

y = 16

Mohan's age = y = 16 years

Rohan's age = x = y+3 = 16+3 = 19 years
