Question

Richa's age was double that of Nitish 2 years ago. if richa was
2 years older to nitesh then how old is richa today​

Answer 1

Answer:6 and 4 years

Step-by-step explanation:

Let the present ages of Richa and Nitesh be x and y years respectively.

By question,2 years ago,

(x-2)=2(y-2).............(1)

(x-2)=(y-2)+2.........................(2)

Using second equation in (1) we get

(x-2)=2{(x-2)-2}

Or, x-2=2x-8

Or, -2+8=x

Therefore x=6 years

And y=(x-2)=(6-2)=4 years
