Solution

The correct option is D 5
Total number of flowers to be planted is 5140.

Number of flowers in each group is 78.

To calculate the number of groups, we have to divide 5140 by 78.

∴ Number of groups $= 5140 \div 78$

Calculating $5140 \div 78$ by standard algorithm, we get:

Now, the multiplication equation can be written in the following way:

$D i v i d e n d = (D i v i s o r \times Q u o t i e n t) + R e m a i n d e r$

So, in this case, the multiplication equation would be:

$5140 = (78 \times Q u o t i e n t) + R e m a i n d e r$

Comparing this to the given equation, $5140 = (78 \times A) + B$ , we find the following:
$A = Q u o t i e n t = 65$
$B = R e m a i n d e r = 70$

Hence, the value of $B - A$ will be $= 70 - 65 = 5$
