Question

Nitish bought a toothpaste that contains 48% of abrasives. If the total weight of the toothpaste is 150 g, then what is the weight of abrasives in the toothpaste?

• A. 72 g
• B. 720 g
• C. 15 g
• D. 48 g

Answer 1

The correct option is A

72 g

Weight of the toothpaste = 150 g
Percentage of abrasives in toothpaste
= 48%

Weight of abrasive $=48\%\text{of}150\text{g}=\frac{48}{100}\times 150\text{g}$
$=\frac{48}{2}\times 3\text{g}\left(\text{Common factor 50}\right)=24\times 3\text{g}=72\text{g}$
