Question

A mixture contains milk & water in the ratio of 5 : 2. If 12 litres of water is added to the mixture the ratio of milk and water will become 4 : 3. Then what will be the quantity of milk in the mixture?

Answer 1

let
quantity of milk be 5x
quantity of water be 2x
acc to que
(5x)/(2x+12)= 4/3
15x=8x+48
15x-8x=48
7x=48
x=48/7
milk =240/7
= 34.2 l

Answer 2

Answer:

34.2

Step-by-step explanation:

5x/(2x+12)  =4/3

15x   =4(2x+12)

15x   =8x+48

7x    =48

x     =48/7

quantity of milk=5x

                         =5 *48/7

                         =240 /7

                         = 34.2
