Let the quantity of milk and water in initial mixture be 3x and 4x respectively. Quantity of milk removed, when 14 litres of mixture is taken out, => (3/7) × 14 = 6 litres Quantity of water removed, when 14 litres of mixture is taken out, => (4/7) × 14 = 8 litres So, => (3x – 6)/(4x – 8 + 14) = 3/5 ⇒ 15x – 30 = 12x + 18 ⇒ 3x = 48 ⇒ x = 16 Initial quantity of mixture = 3x + 4x = 7x = 112 litres
