Question

b) The ratio of milk and water in the mixture of 45 litre is 7:2. If 4 litre more water is added in the mixture, what will be the new ratio of milk and water?
Please with steps

Answer 1

Answer:

$\frac{5}{2}$

Step-by-step explanation:

let the quantity of milk and water be  7x and 2x.

so total solution = 7x +2x = 9x

amount of milk = 7x/9x  *  45

                         =  35 litres

hence amount of water = 45-35 = 10 litres

amount of water added = 4 litre

total amount of water = 10 +4 = 14 litres

new ratio = 35/14 = 5/2

Hope this helps!!!
