In what ratio, a liquid A of cost Rs.31 per litre should be mixed with liquid B of cost Rs.36 per litre, so that the cost of the liquid of mixture is Rs.32.35 per litre?
Cost of 1 litre of liquid A = Rs.31 = cost of cheaper quantity.
Cost of 1 litre of liquid B = Rs.36 = cost of dearer quantity.
Given, mean price = Rs. 32.25
Applying the rule of alligation
Therefore, required ratio = (Cheaper quantity) : (Dearer quantity) = (d - m) : (m - c)
= 3.75 : 1.25 = 3:1.
