IBPS PO Quantitative Aptitude: Percentage, Ratio and Proportion questions with solutions

Q1. A mixture has 60 g of milk and 40 g of water. If 20 g of the mixture is removed, what is the new ratio of milk to water?

1. 3:2
2. 9:6
3. 36:24:00
4. 3:1

Answer: 9:6

The original ratio of milk to water is 60:40 = 3:2. In 20 g of the same mixture, milk removed = 12 g and water removed = 8 g, leaving 48 g milk and 32 g water. The new ratio is 48:32 = 9:6.
