All percentages are in mass% and all quantities are in grams (mass), be sure do not to take volumes into account because mass is 'additive', volumes are not quantitatively additable!
Answer: Take whatever mass of 60 percent solution you have, multiply that mass by 20 (=60-40) and then divide that amount by 40, this is how much water to add to get an 40% solution.
Example: Suppose you have 100 gram of 60% solution, then you should add:
100 * (60-40)/40 = 100*0.50 = 50 gram of water; this is to be added to 100 gram of 60% solution to get (50 + 100 =) 150 gram of 40% solution.
(see on top of the page to know why this calculation method is not valid for 'volumes')

What percent of 60 minutes is 40 minutes?
First we convert 40% to a decimal. we get 40/100 or 0.40 then we multiply it by 60 0.4*60 = 24 so 40% of 60 minuts is 24 minuts
