Answer 2

Assumption

Present age of Nuri be p

Present age of Sonu be n

Five years ago,

Nuri age= (p - 5)

Sonu age= (n - 5)

Situation

⇒(p - 5) = 3(n - 5)

⇒(p - 5) = 3n - 15

⇒ p - 3n = -15 + 5

⇒p - 3y = -10 ….......... (1)

After Ten years

Nuri age= (p + 10)

Sonu's age= (n + 10)

Situation

⇒(p + 10n) = 2(n + 10)

⇒p + 10n = 2n + 20

⇒p - 2n = 20 - 10  

⇒p - 2n = 10 ............ (2)

Subtracting (1) and (2)

⇒(p - 2n) - (p - 3n) = 10 + 10

⇒ -2n + 3n = 20

⇒ n  =  20 …........... (3)

Substituting value in (1),

p - 60 = -10

p =  50

Therefore,

Age of Nuri is 50 years.

Age of Sonu is 20 years.
