Best answer
Correct Answer - Option 3 : 38.4, 1.6 : 0.9

Given:

20 % apple juice is drawn from 60 litres of Apple juice.

Calculation:

First-time apple juice is drawn from 60 litres

20 % of 60 litres = 12 litres

12 liters of Apple juics is drawn from 60 liters

Now, 48 liters are apple juice and 12 liters of water in the jar.

In the second time, 20 % of Apple juice and 20 % of water is drawn.

20 % of 48 litres = 9.6 litres

20 % of 12 litres oof water = 2.4 litres

Apple juice left now = 48 litres – 9.6 litres

= 38.4 litres

Water left = 12 litres – 2.4 litres + 12 litres

= 21.6 litres

Ratio of milk to water : 38.4 : 21.6

= 4.8 : 2.7

= 1.6 : 0.9
