Answer:

Let the Present Age of Sonu be X yrs and Nuri be Y yrs.

Five Years Ago

Nuri = Thrice of Sonu

➻ (Y - 5) = 3(X - 5)

➻ Y - 5 = 3X - 15

➻ Y = 3X - 15 + 5

➻ Y = 3X - 10 ------(¡)

Ten Years Later

Nuri = Twice of Sonu

➻ (Y + 10) = 2(X + 10)

➻ Y + 10 = 2X + 20 --------(¡¡)

Putting the Value of Y from (¡) in (¡¡)

➻ 3X - 10 + 10 = 2X + 20

➻ 3X - 2X = 20

➻ X = 20yrs

Putting x = 20yrs in (¡)

➻ Y = 3X - 10

➻ Y = 3*20 - 10

➻ Y = 60 - 10

➻ Y = 50yrs

★ Present Age

Sonu = 20 years

Nuri = 50 years
