Question

A pack of 2 kg of sugar contains $8\times {10}^6$ crystals and a sack contains 3 packs of sugar.

How many crystals would 12 sacks contain?

• A. 3.88×
• B. 3×
• C. 2.88×
• D. 2×

Answer 1

The correct option is C

2.88×

So we need to find the total quantity of sugar to find out the number of crystals.

Also, 1 sack contains $3\times 2=6$ kg of sugar.

Therefore, 12 sacks would have 72 kg of sugar.

$\Rightarrow \frac{8000000}{2}=\frac{x}{72}$

$\therefore x=2.88\times {10}^{8}crystals.$
