In a mixture of 60 litres the ratio of milk and water is 2:1. If this ratio is to be ...
quantity of water to be further added is :
A. 20 litres
B. 30 litres
C. 40 litres
D. 60 litres
E. 80 litres​

Answer 1

Step-by-step explanation:

Quantity of milk = 60 x 2 litres = 40 litres.

3

Quantity of water in it = (60- 40) litres = 20 litres.

New ratio = 1 : 2

Let quantity of water to be added further be x litres.

Then, milk : water = 40 .

20 + x

Now, 40 = 1

20 + x 2

20 + x = 80

x = 60.

Quantity of water to be added = 60 litres
