Hi ...dear....
here is your answer..

..
the question is Five years old .nuri was thrice as old as sonu . ten years later ,nuri will be twice as old assonu . how old are nuri and sonu.....
sol. ..
Let the age of nuri be x

and the age of sonu be y
according to question,


Five years ago:

Nuri's age = X-5

Sonu's age = Y-5

so,by condition

== (X-5) = 3(Y-5)

== X=3Y-15 + 5

== X= 3Y- 10 ...(1)

Ten years after:

Nuri's age = X+10

Sonu's age = Y+10
(X+10) = 2(Y+10)

X= 2Y+ 20 -10
X = 2Y+10

From eqution(i) X= 3Y- 10

→3Y- 10 = 2Y+10

→3Y- 2Y = 20

→Y = 20

putting value of y in (equation 1

→ X= 3(20)- 10



→ X= 50....

..
hope this helps you!!
