Question

Sara is making icecream. Each batch makes 231 icecreams. If Sara prepares 23 batches, how many icecreams will she have in total?

• A. $5,313$
• B. $5,213$
• C. $5,113$
• D. $5,413$

Answer 1

The correct option is A $5,313$

In one batch total icecreams prepared = $231$
$\therefore$ Icecreams prepared in $23$ batches = $231\times 23$
$=231\times (20+3)$
$=231\times 20+231\times 3$
(Applying distributive property)
$=231\times 2\times 10+231\times 3$
Now multiplying $231\times 2$ and $231\times 3$ one by one as in below figures,


$=231\times 2\times 10+231\times 3$
$=462\times 10+693$
$4,620+693$
$=5,313$

Therefore, Sara have total $5,313$ icecreams.
(a) is the correct option
