Step by step analysis of the problem

**1. If the two digit number is less than 50.** Means that the first digit is either 1, 2, 3 or 4.

**2. The sum of the two digit must be 12**

So the first digit cannot be 1 and 2

Because 1 + 11 give you 12 and 2 + 10 give you 12. 11 and 10 are double digit.

We are left with 3 and 4 for the first digit.

Option 1->

If first digit is 3:

3 + 9 = 12

Option 2->

If first digit is 4:

4 + 8 = 12

**3. Difference of the two digit is 4**

For option 1.

Difference of 3 and 9 is 6. So this is wrong.

For option 2.

Difference of 4 and 8 is 4. So the correct answer is 48
