It looks as though there are 25 21-40 year-olds. 40% of 25 is 10, this is the amount that are AGAINST the increase. Therefore the ones in favor for the increase must be 25 - 10 = 15.

You should be able to follow the same process to get the 41-60 year-olds against an increase. Just be sure to read the given information carefully
