The ratio, by volume, of bleach to detergent to water in a certain solution is 2 : 25 : 100. The solution will be altered so that the ratio of bleach to detergent is tripled while the ratio of detergent to water is halved. If the altered solution will contain 300 liters of water, how many liters of detergent will it contain? Choose the correct choice from the following answers:
A) 40  B) 45  C) 50  D) 75/2  E) 35
B:75/2:W = 2:25:100   Bnew / 75/2new = (1/3)*(2/25) = (2/75)   75/2new / Wnew = (1/2)*(25/100) = (1/8)   Wnew = 300   75/2new = Wnew/5 = 300/8 =75/2   So, answer will be 75/2
