Q1. A is twice as good as B and together they finish a piece of work in 16 days. How many days will A alone take to finish the work?
Answer: 24 days
Explanation: If A is twice as good as B, then A's work rate is 2x and B's is x. Together, they work at a rate of 3x. So, 3x * 16 = work. A's rate is 2x, so 2x * days = work.
