Both of their ages.

\huge \underline \bold \red{Solution \: - }

Solution−

Let the present age of Nuri be = x.

and, let the present age of Sonu be = y.

\huge \underline \bold \red{A/Q,}

A/Q,

\bold \green{(x - 5) = 3(y - 5)}(x−5)=3(y−5)

\bold{x - 3y = - 10..........(i)}x−3y=−10..........(i)

\bold \green{(x + 10y) = 2(y + 10)}(x+10y)=2(y+10)

\bold{x - 2y = 10.........(ii)}x−2y=10.........(ii)

Subtracting (i) from (ii),

we get,

\bold{y = 20...........(iii)}y=20...........(iii)

Putting this value in eq. (i), we get

\bold \green{x - 60 = - 10}x−60=−10

\bold \green{x = 50}x=50

Hence,

Nuri = 50 years....

Sonu = 20 years.....
