Answer 1

Answer:

Nuri's age=50 years

Sonu's age=20 years

Step-by-step explanation:

Let the present age of Nuri be x years and the present age of Sonu be y years.

5 years ago

Nuri's age=x-5 years

Sonu's age=y-5 years

10 years later

Nuri's age=x+10

Sonu's age=y+10

According to question

x-5=3(y-5)

x-5=3y-15

x-3y=-10......(1)

x+10=2(y+10)

x+10=2y+20

x-2y=10.....(2)

From (1) and (2)

y=20 years

x=50 years
