Question

A number decreased from $80$ to $50$. By what percent of its original value has this number decreased? Write answer in the form of the nearest integer greater than the answer.

Answer 1

When the number decreases, it decreases by $30$ only and the original number was $80$

Hence the percentage of decrease $=\frac{30}{80}\times 100=37.5\%\approx 38\%$
