Question

Will mark u my best and brainliest a vessel contains 48 litres of milk and water in the ratio 3 : 1. how much water should be added so that the new ratio becomes 2:5?

Answer 1

Answer:

78 liters

Step-by-step explanation:

Milk:Water = 3:1

Total mixture = 48 liters

∴Milk = (3/4)*48=36 liters

Water = (1/4)*48= 12 liters

Now let us suppose that x liter of water is added

∴Water = 12+x

As per the question

36/(12+x)= 2/5

⇒(12+x)*2=36*5

⇒24+2x=180

⇒2x=180-24

⇒2x=156

⇒x=156/2

⇒x=78

∴78 liters of water shoud be added
