Question

When the phone rings at home, I never let it ring fewer than three times or more than 4 times. Today my little sister, who likes to count everything, told me that the phone rang 17 times and that I answered all the calls. How many times did I answer the phone?

Answer 1

You either answered it 4 times or 5 times.

Answer 2

You answer the phone 5 times:
x=number of calls
17/3.5=x
4.85=x that rounds into 5
