In a can, there is a mixture of milk and water in the ratio 4 : 5. If it is filled with an additional 8 litres of milk the can would be full and ratio of milk and water would become 6 : 5. Find the capacity of the can?
Correct answer: B. 44
- A. 40
- B. 44
- C. 48
- D. 52
Explanation
Let the original milk and water quantities be 4x litres and 5x litres. After adding 8 litres of milk, (4x + 8):5x = 6:5, so 4x + 8 = 6x and x = 4 litres; the capacity is 4(4 + 5) + 8 = 44 litres. The likely wrong answer is 40 litres, which is the original mixture quantity and excludes the added 8 litres.
