From a container having pure milk ,20%is replaced by water and the process os replaced thirce . At the end of operation , the milk is ? Sir can u explain the formula logically
10.13 mins ans is 68. coz we need to add the alcohol which gives 32 % as a concentrate. Already 15% is there which is the amount of 60 ml and now we need find the value of 17% of alcohol concentration (x/400)*100=17% simplifying these equation we get 68 ml that is the concentration we need to add into solution in order to get 32% of alcohol.
No.. You are wrong.. Answer is 100ml only. Nowhere it has mentioned 400ml will be constant. When we increase the alcohol concentration, the total solution value also increases. This can be solved also like below : Initial amount of alcohol is x Let x ml of pure alcohol is to be added. Then, Amount of alcohol becomes 60 + x Total amount of solution becomes 400 + x => (60+x)/(400+x) = 32/100 Solving you will get 100ml as final answer.
