Explanation:
Let the cost of 1 litre milk be Re. 1
Milk in 1 litre mix. in 1st can = 3/4 litre, C.P. of 1 litre mix. in 1st can Re. 3/4
Milk in 1 litre mix. in 2nd can = 1/2 litre, C.P. of 1 litre mix. in 2nd can Re. 1/2
Milk in 1 litre of final mix. = 5/8 litre, Mean price = Re. 5/8
By the rule of alligation, we have:
C.P. of 1 litre mixture in 1st can :=>3/4 1/8
C.P. of 1 litre mixture in 2nd can :=>1/2 1/8
Mean Price :=>5/8
Therefore,Ratio of two mixtures = 1/8 : 1/8 = 1 : 1.
So, quantity of mixture taken from each can = ( 1/2 x 12 ) = 6 litres.
