Correct Answer: A

Solution:

  • Here, expression for the given statement is as follows $ \frac{1}{4}\times \frac{2}{5}\times \frac{30}{100}\times Number=15 $

$ \therefore $ $ \text{Number =}\frac{15\times 4\times 5\times 100}{30\times 2}=500 $

$ \therefore $ 20% of number $ =500\times \frac{20}{100}=100 $
