Question

If by dividing a three-digit number 3BA by 10, we get quotient as 34, then find the values of A and B. [2 Marks]

Answer 1

$\frac{3BA}{10}=34$
Since there is no remainder, 3BA is completely divisible by 10.
If a number is divisible by 10, then the number will have 0 in its ones place.
$\Rightarrow A=0$ [1 Mark]

So,
$\frac{3B0}{10}=34$

$\Rightarrow 3B0=340$
$\Rightarrow B=4$ [1 Mark]
