Find the values of the letters in the following and give reasons for the steps involved.

Solution:

Each letter in the given puzzle must stand for just one digit. 

The operation performed here is addition 

• The addition of A and 5 is giving 2 i.e., a number whose one’s digit is 2. This is possible only when digit A is 7.
• The addition of A (7) and 5 will give 12, and thus, 1 will be the carry for the next step.
• In the next step, 1 + 3 + 2 = 6. Thus, B = 6

Therefore, the addition is as follows:

Hence, A and B are 7 and 6 respectively.
