Answer 1

Answer:

34 litre of water

Step-by-step explanation:

a vessel contain 56 litres of a mixture of milk and water in the ratio 5:2,

5 : 2 = 7parts = 56 litres

1 part = 8 litres

milk = 40 litres

water = 16 litres

water should be mixed with it so that the ratio of milk to water may be 4:5,

40 4

-------- = ------

16+x 5

apply cross multiplication method,

64 + 4x = 200

4x = 136

x= 34 litre of water should be added
