Answer 1

Answer:

HOPE IT HELPS YOU ✌️

Step-by-step explanation:

• Let “V” - Litres of milk-water mixture in the Ratio of 4 : 1, be removed and “V”- Litres of water be added.
• Then (20-V) x 4/5 = 20 x 3/5
• =16- 0.8V= 12
• =0.8V= 4 ;
• ;So V= 4/0.8=5.
• So if we remove 5- Litres of milk-water mixture in the ratio of 4:1, and then add 5- Litres of water, the new mixture will contain milk-water in the ratio of 3 : 2.
