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 = $\frac{30 \times 100}{40} = 75$ %.

Hence, Eduardo's second statement is wrong. (Answer)
