Aeroplane..(Microsoft puzzle)

0 comments


Riddle:
The puzzle question is : On Bagshot Island, there is an airport. The airport is the homebase of an unlimited number of identical airplanes. Each airplane has a fuel capacity to allow it to fly exactly 1/2 way around the world, along a great circle. The planes have the ability to refuel in flight without loss of speed or spillage of fuel. Though the fuel is unlimited, the island is the only source of fuel.


What is the fewest number of aircraft necessary to get one plane all the way around the world assuming that all of the aircraft must return safely to the airport? How did you get to your answer?
Notes:
(a) Each airplane must depart and return to the same airport, and that is the only airport they can land and refuel on ground.
(b) Each airplane must have enough fuel to return to airport.
(c) The time and fuel consumption of refueling can be ignored. (so we can also assume that one airplane can refuel more than one airplanes in air at the same time.)
(d) The amount of fuel airplanes carrying can be zero as long as the other airplane is refueling these airplanes. What is the fewest number of airplanes and number of tanks of fuel needed to accomplish this work? (we only need airplane to go around the world)

Solution: Toggling of 100 switches..

0 comments

Solution:

This is a little tricky. Say switches nos are 1 to 100.
Here
after 1st round, all switches are ON (All were OFF, so toggling will make all ON)
after 2nd round, all switches divisible by 2 (switch no divisible by 2) are TOGGLED
after 3rd round, all switches divisible by 3 (switch no divisible by 3) are TOGGLED
after 4th round, all switches divisible by 4 (switch no divisible by 4) are TOGGLED

Solution: Maximum no. of matches puzzle

0 comments

Solution:
56 points are distributed to 8 team. In the worst case, team0 loses all the games, he gets 0 point. team1 win two games with team0 and loses all other games, he gets 2 points.
In the same way, team2 gets 4 points, team3 gets 6 points. So there are 44 points left which can be distributed to the remaining 4 teams. So the assurance points for a team should be 11 points.
