Question

Which of the following does not have a sum of 6?

2 + 4
8 + (-2)
-4 + (-2)
-2 + 8

Answer 1

Answer:

Since 3 + B given us 1 in the answer, so B has to be 8 as 3+8=11.

Now 1 is carried over so, A+1+2=B

i.e. A+1+2=8. So, A is 5.

Also 6+2=B in hundred's place to confirm that B is 8.

The value of A is 5 and B is 8.
