Question

What are the values of $A$ and $B$?
$A5$
- $BA$
____
$B3$

• A. $A=2$ and $B=2$
• B. $A=2$ and $B=1$
• C. $A=1$ and $B=1$
• D. $A=0$ and $B=2$

Answer 1

The correct option is B $A=2$ and $B=1$

$A5$
$-$$BA$
____
$B3$
The subtraction of $5$ and $A$ is giving 3 i.e., $5-A=3$
The above condition is possible only when digit $A$ is $2$, because $5-2=3.$
The next step to get the value as B as $A-B=B$. This is possible if $B=1$.
Therefore, the subtraction is as follows:
$25$
- $12$
____
$13$
The value of $A=2$ and $B=1$

So, option B is correct.
