Eduardo says that an increase from 10 to 40 is 300% therefore a decrease from 40 to 10 must be a 300% decrease do you agree with

Answer:

Eduardo's second statement is wrong.

Step-by-step explanation:

Eduardo says that an increase from 10 to 40 is 300% which is true. Because there is an increase by (40 - 10) = 30 and the percent of increase is calculated with respect to 10.

So, % of increase = $\frac{30 \times 100}{10} = 300$ %.

But when we consider a decrease from 40 to 10, then the decrease is by (40 - 10) = 30, but the percent of decrease will be calculated with respect to 40.

Therefore, the % decrease = $\frac{30 \times 100}{40} = 75$ %.
