Question

The age of Jaya 10 years ago is equal to Ritu present age. The sum of Jaya's age 8 years hence from today and Ritu age 12 years ago is 90 years then what was age of Neha 13 years ago from now if Neha is 9 years younger than Ritu?

Answer 1

Answer 20 years

Step-by-step explanation:

Let

Age of jaya be x and age of ritu be y

So

A.t.q

X-10=y .......(1)

And

(X+8) + (y-12) = 90

Putting eq 1

We get

X+x+8-10-12=90

2x-14=90

2x=104

X=52

And y =52-10=42

Now

Neha age is 9 year less than ritu

So neha present age is 42-9=33

13 years ago

33-13 =20 years
