Question 5
Along the path between Alice’s house and Ben’s house is a line of flowers consisting of 25 peonies and 25 tulips. One day, Alice walks from her house toward Ben’s house, watering the flowers one by one as she encounters them. After watering the 20th tulip, her water runs out, leaving exactly 10 flowers unwatered. The next day, Ben walks from his house toward Alice’s house, picking the flowers one by one as he encounters them. After picking the 6th tulip, he decides that he has enough flowers for a bouquet. How many flowers remain along the path?
