Question

a mixture contains milk and water in the ratio of 5:2 on adding 63 litters of water the ratio of milk to water becomes 2:5 find the difference between milk and water in final mixture

Answer 1

45 liters will be the answer

Answer 2

Before :

Milk : Water = 5 : 2

Multiply the ratio with a factor of 2

Milk : Water = 10 : 4

After :

Milk : Water = 2 : 5

Multiply the ratio with a factor of 5

Milk : Water = 10 : 25

Since no milk is added, we know that the ratio of water has increased from 4 to 25

Find the parts that made up 63 liters of water:

25 - 4 = 21

21 parts = 63

Find 1 part:

1 part = 63 ÷ 21 = 3

Find 10 parts (Milk):

10 parts = 3 x 10 = 30

Find 25 parts (Water):

25 parts = 3 x 25 = 75

Difference between the milk and water = 75 - 30 = 45 liters

Answer: 45 liters
