Question
Three mixtures: A, B, and C containing 25%, 35%, and X%
of water, respectively. If all these mixtures are mixed in the ratio of 1:3:2 to form a resultant mixture, and the resultant mixture contains 30% of water in it, then find the value of X.Solution
ATQ, Let the quantity of mixture A, B, and C mixed be 100 litres, 300 litres, and 200 litres, respectively. Quantity of water in mixture A, B, and C is 25 litres, 105 litres, and 2X litres, respectively. According to the question, (25 + 105 + 2X)/600 = 30/100 130 + 2X = 180 2X = 50 X = 25
