A container contains total 120 liters mixture of milk and water in which quantity of water is 20 liters. If 36 liters mixture taken out from container and 6 liters milk added, then find quantity of water in what percent (approximate) less than that of milk in final mixture?

82%

88%

78%

86%

90%

Explanation:

Ratio of milk to water in mixture = (120 – 20) : 20 = 5 : 1
Total water in final mixture = 20 - 36 × 1 /6 = 14 liters
Total milk in final mixture = 100 - 36 × 1/ 6 + 6 = 76 liters
Required percentage = (76−14)/ 76 × 100 = 81.67 = 82%
