Question

The ratio of water and milk in a 30 litre mixture is 7:3, find the
quantity of water to be added to the mixture in order to make
this ratio 6:1.​

Answer 1

Answer:

Here,Let water = 7x and milk = 3x

Now,

7x + 3x = 30

x = 3

So, water = 7x = 7 × 3 = 21 liter

Milk = 3x = 3 × 3 = 9 liter

Now, we keep milk constant and add water to mixture to get ratio 6 : 1

Let water in this mixture = 6y and milk = y

We have, milk = 9 liter, so y = 9 liter

Water = 6y = 6 × 9 = 54 liter

Then extra water to be added is 33 liter
