1. An empty pool is being filled with water at a constant rate. It takes 9 hours to fill 3/5 th of the pool. How much more time will it take to compeletely fill the pool?
- A. 15
- B. 15
- C. 15
- D. 15
Answer: Option A
Explanation:
***This question is erroneous....
Part of the pool remaining to be filled = 1 - 3/5 = 2/5
3/5 of the pool can be filled in 9 hours
So, the entire pool can be filled in 9×5/3 = 15 hours
