# Confusing Ferris Wheel

Logic
Logic puzzles require you to think. You will have to be logical in your reasoning.

There are 10 two-seater cars attached to a Ferris wheel. The Ferris wheel turns so that one car rotates through the exit platform every minute. The wheel began operation at 10 in the morning and shut down 30 minutes later. What's the maximum number of people that could have taken a ride on the wheel in that time period?

### Hint

If the wheel has to stop promptly at 10:30, then the operator won't allow anyone on who can't get off the Ferris wheel by 10:30.### Answer

42For the first nine minutes it's moving, the cars are arriving at the unloading zone are unoccupied. For the last nine minutes, of operation, no one will be able to get on the ride.

From the time the Ferris wheel fills up at 10 minutes past the hour until the last passenger steps off at 10:30, a total of 21 sets of passengers will have taken a ride.

Fun and challenging teaser.

very challenging

This teaser was on Professor layton and the curious village XD

there are 2 ways you could read the question. I thought it meant that one car's rotation is a minute long, not that one car stops, and a minute later the next one stops. so my answer was 360 people.
