Question

Mohit is twice as old as his cousin Ruchi is now. If Mohit is also 3 years old then Ruchi find the ages in linear equation

Answer 1

Answer:6 years and 3 years

Step-by-step explanation:

Let the age of Mohit be x and that of Ruchi be y.

Then X = 2 Y or x-2y = 0 (I)

And

X-Y = 3 (ii)

Taking opposite sign in equation (ii)

x-2y=0

-x+y=-3

x-x is cancelled

And -y =-3

So y = 3 ( Ruchi's age)

Mohit's age =3×2=6 years
