Question

Find the value of the letters in each of the following and give reasons for step involved

Answer 1

Answer:

There are two letters whose values are to be found out. Study the addition in the ones column, i.e., from A + 5 we get 2, i.e., the number whose ones digit is 2.

For the to happen, A must be 7

(∴ A + 5 = 7 + 5 = 12).

So for the addition in tens column, we have

1 + 3 + 2 = B ⇒ B = 6

So, the puzzle has been decoded as

∴ The possible values of A and B are 7 and 6 respectively.
