Water man has 2 cans of water. The 1st contains 25% water and the rest milk. The 2ndcontains 50% water. How much milk should he mix from each of the containers so as to get 12ltr of water such that the ratio of milk to water is 3 : 5? Choose the correct choice from the following options
A) 4 ltr  B) 5 ltr  C) 6 ltr  D) 7 ltr  E) 9 ltr
Let the cost of 1 litre milk be Re. 1   Milk in 1 litre mix. in 1st can =	3	litre, C.P. of 1 litre mix. in 1st can Re.	3   4	4   Milk in 1 litre mix. in 2nd can =	1	litre, C.P. of 1 litre mix. in 2nd can Re.	1   2	2   Milk in 1 litre of final mix. =	5	litre, Mean price = Re.	5   8	8   By the rule of alligation, we have:   C.P. of 1 litre mixture in 1st can C.P. of 1 litre mixture in 2nd can   3   4   Mean Price   5   8   1   2   1   8   1   8   Ratio of two mixtures =	1	:	1	= 1 : 1.   8	8   So, quantity of mixture taken from each can = 1	x 12 = 6 ltr.   2   6 ltr
