Explanation

Initially, milk is 108 x 5/9 = 60 litres and water is 48 litres. After adding the stated amounts, milk is 80 litres and water is 84 litres, so their difference is Y = 4 litres. Therefore, 7Y = 28.

AI explanation

In the initial 108 litres of mixture with a ratio of 5 : 4, there are 60 litres of milk and 48 litres of water. After adding 20 litres of milk and 36 litres of water, the new amounts are 80 litres of milk and 84 litres of water. The difference Y between these amounts is 84 minus 80, equaling 4. Therefore, 7Y is 7 multiplied by 4, which is 28.
