Question 52
Find the value of the letters in the following question:
1 B A+A B A________ 8 B 2
We have, 1 B A+A B A________ 8 B 2
Here, A + A is a number whose one's digit is 2, therefore A = 6.
Now, B + B + 1 = B
So, the possible value of B is 9.
Again, in third column.
A + 1 + 1 = 8
⇒ A = 6, which is true.
Hence, A = 6, and B = 9
