Plz solve 2nd part of que no 2

Dear Student,

Let the present age of Nuri be X

and the present age of Sonu be Y

Now, ATQ

Five years ago:

Nuri's age = X-5

and Sonu's age = Y-5

so,

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

or,  X=3Y-15 + 5

or, X= 3Y- 10 ........................... (i)

Ten years after:

Nuri's age = X+10

and Sonu's age = Y+10

 (X+10) = 2(Y+10)

or, X= 2Y+ 20 -10

or, X = 2Y+10

From equation(i) X= 3Y- 10

or, 3Y- 10 = 2Y+10

or, 3Y- 2Y = 10 + 10

or, Y = 20

Now putting value of Y in (i)

or, X= 3(20)- 10

or, X= 60-10

or, X= 50

So, Nuri is 50 years old and sonu 20 Years old.

Regards!
