The answer is $100 %$ $100%$ .

First, we have to calculate how much the number has increased

$increase = 40 - 20 = 20$ $"increase" = 40-20=20$

$20$ $20$ is the increase in the original number. So we can calculate the percent change by using the formula

$% change = \frac{Increase or decrease in no}{orignal no} \times 100 %$ $"% change" = "Increase or decrease in no"/"orignal no" xx 100%$

So

$% change = \frac{20}{20} \times 100 % = 100 %$ $"% change" = 20/20 xx100%=100%$

The answer is $100 %$ $100%$ .
