Nice Answer Brother, But you have formed the second equation wrong
After 10 years, ages will be (x+10) and (y+10)
By mistake you took (x+5) and (y+5)
Please edit and correct your answer
Oh....ya im sorry...thats by mistake.

Hey Sowmiya,
Here, we can solve the question like this:
Let Present Age of Nuri = x
and Present Age of Sonu = y
Five years ago,
Age of Nuri = x - 5
Age of Sonu = y - 5
At that time, Age of Nuri was thrice that of Sonu. So we have:
x - 5 = 3(y - 5)
So, x - 5 = 3y - 15
So, x = 3y - 10 -----(1)
After Ten Years,
Age of Nuri = x + 10
Age of Sonu = y + 10
At that time, age of Nuri is twice that of Sonu. So we have:
x + 10 = 2(y + 10)
So, x + 10 = 2y + 20
So, x = 2y + 10
Putting x = 3y - 10 from equation (1)
We have:
3y - 10 = 2y + 10
So, y = 20
Put this in (1)
x = 3y - 10
So, x = 60 - 10
So, x = 50
Thus, we have our answers:
Present Age of Nuri = 50 years
Present Age of Sonu = 20 years
Hope this helps
