Question

solve this plzzz?........

Answer 1

Let the ten's digit be x and the one's digit be y.

The original number will be 10x + y and reversed number is 10y + x.

Given 7(10x+y) = 4(10y+x)

          70x + 7y = 40y + 4x

           66x - 33y = 0

           2x - y = 0

            2x = y  ------------- (1)

Given that the difference of the digit is 3.

y - x = 3

2x - x = 3

x = 3

substitute x = 3 in (1), we get

y = 6.

The number is 36.
