Question

Good morning everyone....!!
Solve it plsss.....!!
I want it to be solved in only 1 variable.....!!​

Answer 1

Answer:

5 years, 10 years

Step-by-step explanation:

Let age of anushka = x.

If he is now twice as old as she is,

Then, Age of hari = 2x

3 years Ago :

Age of anushka = x - 3

Age of hari = 2x - 3

Hari was 5 years older than Anushka.

=> (2x - 3) = (x - 3) + 5

=> 2x - 3 = x - 3 + 5

=> 2x - 3 = x + 2

=> x = 5

Then,

2x = 10

Therefore,

Age of Hari = 10 years

Age of Anushka = 5 years

Hope it helps!

Here is your answer mate.....

$\huge\bold\purple{Solution..}$

Let Hari's present age be 'X'

Let Anushka's present age be ' Y '

So,three years ago,Hari's age was:

(X-3) years.

Three years ago Anushka's age was:

(Y-3) years.

First equation is:

(X-3)=(Y-3)+5

or, X -3 = Y -3+5

or, X-3=Y+2

or, X =Y+2+3

So, X = Y +5..............(i)

Second equation is:

X =2Y

By substituting the value of equation (i) here we get,

Y+5=2y

or, Y-2Y=-5

or, -Y=-5

So, Y =5.

Then by substituting the value of Y into the 1st equation we get,

X =5+5

So,X =10.

So,Hari's present age is: 10 years.

Anushka's present age is: 5 years.
