A dishonest milkman claims to sell his milk at cost, but he inflates the price by 25% by mixing it with water. The water content of the combination is:
A. 4% B. 6% C. 20% D. 25%
Explanation: Let Re. 1 be the C.P. of 1 litre milk.Then, for 1 litre of combination, S.P. = Re. 1, Gain = 25%.1 litre mixture C.P. = Re. 100/125 x 1 = ⅘,As a result of the alligation rule, we have:Milk to water ratio = 4/5 : 1/5 = 4 : 1.As a result, the percentage of water in the combination is 1/5 x 100% = 20%.
