### Explanatory Answer

##### Method of solving this CAT Question from Ratio, Mixtures and Averages: When we mix two mixtures in a particular ratio, we get a third mixture. Given the third mixture how does one find the ratio in which they were mixed.

C.P. to get 30% profit at Rs 18/litre = $$frac{18}{1.3}\\$ = $\frac{180}{13}\\$ Therefore, => $\frac{15}{13}\\$ : $\frac{180}{13}\\$ => 1: 12 Note: Make sure you don’t mark 12:1 since in the question, water has been mentioned first. This can be a silly trap to fall into after all the hard work. The question is "What is the ratio in which water should be mixed with a coke concentrate costing Rs 15/litre to make a profit of 30% by selling the resultant drink at Rs 18/litre?" ##### Hence, the answer is "1:12". Choice D is the correct answer. ###### Online CAT CoachingTry it free!
