Question

A box contains $25$ strips having $12$ capsules of $500mg$medicine in each capsule. Find the total weight in grams of medicine in $30$ such boxes.

Answer 1

Step I - Box contains a number of strips = $25$

Each strip has a number of capsules = $12$

Each capsule has medicine = $500mg$

Total weight in $30$ such boxes = $25\times 12\times 500\times 30$

Step II - Let's make the suitable pair to multiply.

$25\times 12\times 500\times 30$ = $(25\times 12)\times (500\times 30)$

= $300\times 15000$= $4500000mg$

Step III - Convert the $mg$ into gram. As we know that $1mg=\frac{1}{1000}gram$

So, $4500000mg$ = $\frac{4500000}{1000}$= $4500gram$

Hence, the total weight in grams of medicine in $30$ such boxes =$4500gram$.
