Find the values of the letters in the following and give reasons for the steps involved
Each letter in the given puzzle must stand for just one digit.
The operation performed here is addition
- The addition of B and 1 is giving 8 i.e., a number whose one’s digits is 8. This is possible only when digit B is 7. In that case, the addition of B and 1 will give 8.
- In the next step, A + B = 1. Clearly, A is 4 as B is 7 i.e., 4 + 7 = 11 and 1 will be a carry for the next step.
- In the next step, 1 + 2 + A = B i.e., 1+ 2 + 4 = 7
Therefore, the addition is as follows:
Hence, the values of A and B are 4 and 7 respectively.
