Question

Answer 1

Answer:

see this answer

Step-by-step explanation:

Solution:

This has two letters A and B whose values are to be found.

The addition in the ones column:

The sum of three A's is a number whose ones digit is 0.

Therefore, the sum of two A's must be a number whose ones digit is 0.

This happens only for A = 0 and A=5.

IfA=0

Then the sum is 0+0+0=0, which makes B =0 too.

It makes A = B, and then the tens digit of BA too becomes 0),

So, we reject this possibility. So, A=5.

Therefore, the puzzle is solved as shown below.

\: \: 55

+ 5+5

+ 5+5

Answer=15

That is A=5 and B =1
