Answer 2

Hi praneeth,

The sum of digits of a two digit number is 9.
The difference between second digit and first digit is 3.

Let the digits are x,9-x

The difference between second digit and first digit is 3.

Means (9-x)-x=3
9-x-x=3
9-2x=3
9-3=2x
2x=6
x=3

The other digit is 9-x=9-3=6

Therefore the digits of a two digit number are 3 and 6.

The number is 36.

hope it helps
