Answer with Explanation:
Let C.P. of 1 litre milk be Re. 1.
S.P. of 1 litre of mixture = Re.1, Gain = 50/3 %.
Therefore,
C.P. of 1 litre of mixture = (100 x 3/350 x 1) = 6/7
By the rule of Alligation, we have:
C.P. of 1 litre of water 0 1/7
C.P. of 1 litre of milk Re.1 6/7
Mean Price Re.6/7
Therefore,Ratio of water and milk = 1/7 : 6/7 = 1 : 6.
Let C.P. of 1 litre milk be Re. 1.
S.P. of 1 litre of mixture = Re.1, Gain = 50/3 %.
Therefore,
C.P. of 1 litre of mixture = (100 x 3/350 x 1) = 6/7
By the rule of Alligation, we have:
C.P. of 1 litre of water 0 1/7
C.P. of 1 litre of milk Re.1 6/7
Mean Price Re.6/7
Therefore,Ratio of water and milk = 1/7 : 6/7 = 1 : 6.
