Multiple choice

There were 120 litres of pure milk in a vessel. Some quantity of milk was taken out and replaced with 23 litres of water. thus the resultant ratio of the quantity of milk to water is 4:1. Again 23 litres of the mixture was taken out and replaced with 28 litre of water. What is the ratio of the milk to water in the resultant mixture? एक बर्तन में 120 लीटर दूध है | दूध की कुछ मात्रा निकाली जाती है और 23 लीटर पानी को मिलाया जाता है इस तरह दूध और पानी का अनुपात 4 : 1 हो जाता है |पुनः 23 लीटर मिश्रण निकाला जाता है और 28 लीटर पानी मिलाया जाता है |परिणामी मिश्रण में दूध और पानी का अनुपात क्या है ?

  1. 15 : 13

  2. 46 : 29

  3. 48 : 29

  4. 29 : 44

B Correct answer
Explanation

Starting with 120L pure milk. After removing some milk and adding 23L water, milk:water = 4:1, so milk = 96L, water = 24L. Then 23L of this mixture (with milk:water = 4:1) is removed, so 18.4L milk and 4.6L water removed. Remaining: 77.6L milk, 19.4L water. Adding 28L water: 77.6L milk, 47.4L water. This ratio is approximately 46:29. Option B is correct.
