• B. 36 : 13
• C. 34 : 9
• D. 35 : 13

Answer 1

Answer:

D. 35 : 13

Let the quantity of milk and water be 4x and x respectively Quantity of milk = (4x/5x) × 50 litres = 40 litres Quantity of water in mixture = (50 – 40) litres = 10 litres Quantity of milk taken out from mixture = 10 × (4/5) = 8 litres Quantity of water taken out in the mixture = 10 × (1/5) = 2 litres New quantity of milk in the mixture = (40 – 8) = 32 litres New quantity of water in the mixture = (10 – 2) = 8 litres New ratio = (32 + 3) : (8 + 5) = 35 : 13
