You have 240 barrels of wine, one of which has been poisoned. After drinking the poisoned wine, one dies within 24 hours. You
have 5 slaves whom you are willing to sacrifice in order to determine
which barrel contains the poisoned wine. How do you achieve this in 48
missionaries and three cannibals must cross a river. There is a single
boat which can carry a maximum of two people and there must be at least
one person on board (the boat cannot cross by itself).
either bank, if there are missionaries present, the count of
missionaries must be equal or greater than the count of cannibals, else
the cannibals would eat them.
Three cannibals and three anthropologists have to cross a river.The boat they have is only big enough for two people. The cannibals will do as requested, even if they are on the other side of the river, with one exception. If at any point in time there are more cannibals on one side of the river than anthropologists, the cannibals will eat them.
What plan can the anthropologists use for crossing the river so they donâ€™t get eaten?
Note: One anthropologist cannot control two cannibals on land, nor can one anthropologist on land control two cannibals on the boat if they are all on the same side of the river. This means an anthropologist will not survive being rowed across the river by a cannibal if there is one cannibal on the other side.
Youâ€™re in a room with three light switches, each of which controls one of three light bulbs in the next room. You need to determine which switch controls which bulb. All lights are off to begin, and you canâ€™t see into one room from the other. You can inspect the other room only once. How can you find out which switches are connected to which bulbs?
There are three boxes, one
contains only apples, one contains only oranges, and one contains both
apples and oranges. The boxes have been incorrectly labeled such that no
label identifies the actual contents of its box. Opening just one box,
and without looking in the box, you take out one piece of fruit. By
looking at the fruit, how can you immediately label all of the boxes
You have a 100 coins laying flat on a table, each with aÂ head side and a tail side. 10 of them are heads up, 90 are tails up. You can't feel, see or in any other way find out which side is up. Split the coins into two piles such that there are the same number of heads in each pile.
It is raining heavily and you are in a two-seater car, and you see your best friend, your crush and an old lady waiting for the bus in a bus stand. And as it is raining there is very less possibility of the bus to arrive for the next 2 hours. Your best friend is having a very important interview, your crush is lonely and afraid and the old lady needs to visit the hospital and needs medical attention.
