Question

container has 84 litre of mixture consisting of milk and water in the ratio 5:2 how much more water should be added so that the ratio become 2:1

Answer 1

Answer:

Here

Here let

milk=5x

water=2x

ATQ

5x+2x=84

or, 7x= 84

or, x=84/7

:. x= 12

Hence,

milk=5x= 5×12= 60

water=2x= 2×12= 24

Also ,

water should be added =24+ x

Now,

Now, according to the question

60/(24+ x)=2/3

or, 60×3=2(24+ x)

or, 180=48+ x

or, 180-48= x

:. x = 132

Hence,

132 l should be added
