 \sf\small\green{Given:-}

  • Let numbers be x at onces place.

  • tens place so, 10y + x is the digit.

\sf\small\green{Find:-}

  • If the difference between the digits is 3 then find the number.

\sf\small\green{Solution:-}

According to the question,

\sf\therefore 7(10y + x) = 4(10x + y)

⇒x=2y⟶(i)

Now,

 \sf x - y = 3

From equation

( I ) 2y=x substitute in above equation.

 \rightarrow \sf \ \: 2y - y = 3

 \rightarrow \sf \: y = 13

Required original no: is =10y+x=10⋅

3+6=36
