Question

I am a 2-digit number. If sum of my two digits is added to the product of my digits, it is me again. Can you find me?

Answer 1

Answer: 49

Explanation:

4x9=36

4+9=13

36+13=49

Answer 2

Explanation:

Let “ab” represent the digits of the number.

a ≠ 0

Value of the number = 10a+b

a+b + ab = 10a + b

a + ab = 10a

ab = 9a

b = 9

“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99
