The answer is #100%#.

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

#"increase" = 40-20=20#

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

#"% change" = "Increase or decrease in no"/"orignal no" xx 100%#

So

#"% change" = 20/20 xx100%=100%#

The answer is #100%#.
