Answer 1

Answer:

7:18

Step-by-step explanation:

90 Litre Milk 10 Litre water

total = 100 Litre

Sold = 1/5th = 20 Litre

Milk Sold 18 Litre & Water Sold = 2 Litre

Reaming Milk  = 72 Litre

Remaining Water = 8 Litre

Water Added again = 20 Litre

Now water = 8 + 20 = 28 Litre

Ratio of water to Milk

28:72

7:18
