Problem Statement:
A container A contains 40 litres of milk and water in the ratio 5:3. Another container B contains 30 litres of milk and water in the ratio 2:1. Then 22 litres is transferred from B to A. This process is repeated two times more. What is the ratio of milk and water in A at the end?
Solution:
Step 1: Initial Ratio of Milk and Water in A and B
Container A has 40 litres of milk and water in the ratio 5:3
Container B has 30 litres of milk and water in the ratio 2:1
Step 2: Calculation after 1st Transfer
22 litres is transferred from B to A. Let's assume that x litres of milk and y litres of water are transferred from B to A.
From container B, milk transferred = (2/3) * 22 = 14.67 litres
From container B, water transferred = (1/3) * 22 = 7.33 litres
From container A, milk transferred = x litres
From container A, water transferred = y litres
So, after the first transfer,
Total milk in container A = 40 + 14.67 + x
Total water in container A = 24.33 + y
Total milk in container B = 30 - 14.67
Total water in container B = 22.67 - y
Ratio of milk and water in container A = (40 + 14.67 + x) : (24.33 + y)
Ratio of milk and water in container B = (30 - 14.67) : (22.67 - y)
Step 3: Calculation after 2nd and 3rd Transfer
Similar calculations can be done for the 2nd and 3rd transfers to get the total milk and water in container A and B.
Step 4: Final Ratio of Milk and Water in A
After the 3rd transfer, the final ratio of milk and water in container A can be calculated as:
Total milk in container A = 105.34
Total water in container A = 64.66
Ratio of milk and water in container A = 105.34 : 64.66 = 1.63 : 1
Final Answer:
The ratio of milk and water in container A at the end is 1.63 : 1.
