Question

If the 3 digit number "3BA" on divided by 10 gives 34 without leaving any remainder, then the value of A + B is:

• A. 4

Answer 1

The correct option is A 4
Given: $\frac{3BA}{10}=34$
Since there is no remainder, 3BA is completely divisible by 10.
Now we know that all numbers exactly divisible by 10 will have 0 in the one's place.
$\Rightarrow$ A = 0
Now $\frac{3B0}{10}=34$

So, 3B = 34
$\Rightarrow$ B = 4

Therefore, the value of A+B = 0 + 4 = 4
