Question

Arrange the following in the increasing order of their values from top to bottom.

• A. 50% of 80
• B. 30% of 100
• C. 25% of 200
• D. 20% of 500

Answer 1

$\text{50\% of 80}=\frac{50}{100}\times 80=40\text{20\% of 500}=\frac{20}{100}\times 500=100\text{25\% of 200}=\frac{25}{100}\times 200=50\text{30\% of 100}=\frac{30}{100}\times 100=30$

So, the increasing order of their values is 30<40<50<100.
