Question

Find the values of the letters A and B:

• A. A = 5, B = 2
• B. A = 3, B = 6
• C. A = 2, B = 4
• D. A = 2, B = 5

Answer 1

The correct option is D A = 2, B = 5

In the tens column, we know A can be either 2 (because if 1 is carried forward from the ONES column, then 1 + 2 + 3 = 6) or A can be 3 because 3 + 3 = 6.

If we assume A to be 3, in that case B has to be 6 and then 6 + 7 = 13, and 1 carried forward from here will give us 1 + 3 + 3 = 7 (tens column) so A cannot be 3.

So, A has to be 2 only, and then B will be 5.

So, the correct answer is option -C.
