The farmer dies, leaving behind three sons, 17 cows and the following order:
Now the three don't know what to do. So they ask an old friend of the family, which knows a solution such that everyone is happy.
What did he propose?
There are twenty flat plates with one side painted as blue and other side painted as red. Plates are randomly arranged such that 10 blue and 10 red surfaces are on the top. This table is moved in completely dark room. You must create two sets of plates with each set having the same number of blue and red top as the other group. You can only move or flip the plates; you are unable to determine their current state. How do you create two even groups of plates with the same number of blue and red in each group?
Four people need to cross a rickety bridge at night. Unfortunately, they have only one torch and the bridge is too dangerous to cross without one. The bridge is only strong enough to support two people at a time. Not all people take the same time to cross the bridge. Times for each person: 1 min, 2 mins, 7 mins and 10 mins. What is the shortest time needed for all four of them to cross the bridge?
