A) 24 B) 54 C) 30 D) 36 Correct Answer : 36 Explanation :Ratio of milk and water in jar A = 180 L : 36 L = 5 : 1 Let, x L of mixture taken out from jar A. So, Quantity of milk taken out from jar A = x*5/6 = 5x/6 and Quantity of water taken out from jar A = x*1/6 = x/6 Now, according to the question, (5x/6) / (x/6 + 6) = 5/2 (5x/6) / (x + 36)/6 = 5/2 5x / (x + 36) = 5/2 10x = 5x + 180 5x = 180 x = 36 Hence, 36 L of mixture was taken out from Jar A.
