• A. $16$
• B. $40$
• C. $14$
• D. $4$

Answer 1

The correct option is B $40$

Say:
There are $356$ candies.
Nutsy wants at least $756$ candies for his shop.
Let us calculate the additional number of candies Nutsy needs by expanding the numbers.
Steps:
$356=300+50+6$
$756=700+50+6$
So, number of more candies needed $=756–356=400$
$1$ hundred $=10$ tens
So, $4$ hundreds $=4$ times $10=40$ tens
Hence, $40$ packets of $10$ candies each are needed.
Option D is the correct answer.
