Answer:

Let present age of sonu x

Let present age of niru y

\\

\large{\underline{\mathrm{\green{According\:\:to\:\:the\:\:given\:\:information:-}}}}

 \\  \\  \sf  x - 5 = 3 \: (y - 5) \\  \\  \\  \implies \sf \: x - 3y =  - 10  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \qquad(i)\\  \\  \\  \implies \sf \: x + 10 = 2(y + 10) \\  \\  \\  \implies \sf \: x - 2y = 10 \quad \qquad \quad \:  \:  \:  \:  (ii) \\  \\

Subtracting equation (1) from equation (2), we obtain :

\\

  • y = 20(3)

\\

Substituting it in equation (1), we obtain :

\\

 \sf \: x - 60 =  - 10 \\  \\  \\   \sf \blue{x = 50} \\  \\

\\

Hence,

\\

  • Age of nuri = 50 years
  • Age of Sonu = 20 years
