anonymous · Answer

You're on the right track by thinking about an example. If his salary was 100, and it goes up by 40%, then it's 140. So what % will it have to go down by from 140 to get back to 100? You'll want it to decrease by 40, so find out what percentage 40 is of 140 and that will be your answer.

anonymous · Answer

40 is 28. something % of 140 so 28% must be decreased.
