Q1. A is twice as good as B and together they finish a task in 14 days. How many days will A take to finish the task alone?
Answer: 21 days
Explanation: Let's denote B's rate as x. A's rate is 2x. Together, they work at a rate of 3x. Since they finish the task in 14 days, their combined rate is 1 / 14 of the task per day.
