Ratio of milk and water in a mixture is = 4x : 3x
According to the question
4x/(3x + 2) = 8/7
⇒ 4x × 7 = 8 (3x + 2)
⇒ 28x = 24x + 16
⇒ 28x – 24x = 16
⇒ 4x = 16
⇒ x = 16/4
⇒ x = 4
Quantity of mixture in the last = (4x + 3x) = 7x = 7 × 4 = 28 litres
Quantity of mixture in the last = 28 + 2 = 30 litres
