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×

We need to find the total quantity of sugar to find out the number of crystals.
1 sack contains 6 kg of sugar.
Therefore, 12 sacks would have 72 kg of sugar.

$x=\frac{8000000\times 72}{2}$
Therefore, $x=2.88\times {10}^8$ crystals.
