Question

5 years ago nuri was thrice as old as sonu 10 years later nuri will be twice as old as sonu how old are nuri and sonu

Answer 1

Answer:

Let Nuri's present age be x years

let sonu's present age be y years

5 years ago:

Nuri's age would have been x-5

Sonu's age would have been y-5

10 years later:

Nuri's age will be x+10

Sonu's age will be y+10

ATQ

x-5=3(y-5)

x-5=3y-15

15-5=3y-x

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

x+10=2(y+10)

x+10=2y+20

x-2y=10 ------2.

Adding 1. and 2.

-x+3y=10

x-2y=10

-------------

y=20

Put y=20 in 2.

x-2(20)=10

x-40=10

x=50

Nuri's age is 50 years

Sonu's age is 20 years
