Question

In a mixture of 60 litres, the ratio of milk and water is 2 : 1 what amount of water must be added to make the ratio of milk and water as 1 : 2?

Answer 1

Let the ratio of milk to water be x

2x + x = 60
3x = 60
x = 20

Milk = 2x = 40litre
Water = x = 20litre

Let x amount of water must be added to make the ratio of milk and water as 1 : 2

40/20 + x = 1/2
Cross multiply

80 = 20 + x
60 = x

60 litre of water must be added to make the ratio of milk and water as 1 : 2

Answer 2

Answer:

Step-by-step explanation:

2x + x = 60

3x = 60

x = 20

Milk = 2x = 40litre

Water = x = 20litre

Let x amount of water must be added to make the ratio of milk and water as 1 : 2

40/20 + x = 1/2

Cross multiply

80 = 20 + x

60 = x

60 litre of water must be added to make the ratio of milk and water as 1 : 2
