Question 423635

let assume digits unit digit is y and tens digit is x.

case 1:  when x-y = 2  (i.e  x is greater than y)

10x+y = 5(x+y)-3

=> 10x + y = 5x+ 5y -3

=> 5x -4y = -3

after solving...

x = -11, y = -13

it is not possible...


case 2: when y -x =2  (i.e y is greater than x)


10x+y = 5(x+y) -3


after solving value of x and y.

x = 5, y = 7


so, required number is : 57
