Time management

Try this simple puzzle, see how good is your time management.


|[A 2 minute] |
|[B 4 minute] |
|[C 8 minute] |
|[D 16 minute] |

There are four boats on the left bank of a river. To cross the river to the right bank, Boat A takes 2 minutes; Boat B takes 4 minutes; Boat C takes 8 minutes and Boat D takes 16 minutes.

All boats need to go to the right bank but there are only one boatman. One boat can pull another boat but it will take the same amount of time as the slower of the two boats to cross the river.

If the boatman uses one boat to pull another boat to the right bank and returns to the left bank in one boat, how many minutes will it take for him to move all the boats to the right bank?


Try this puzzle and find out how good is your IQ and also maybe your time management.

Most of the time we are rushing for the deadline. If you manage to plan your schedule we can somehow shortcut lots of unnecessary wastage. Everyone can reach to the destination at same time and we can cheer for all the handwork that we had contributed to the project.

A project without coordination is a war field, everyone is your enemy. You need to act fast or else you will lose your territory and by then you are dead meat.

So you can choose either to work together or play the war game in your project. Good luck.

    the boatman can do it at 32 mins, but dinstein can do it better.

    when the other party is very oppressive, we have to defend ourselves. No choice, we don't like to start a war, but patient has its limit. War is imminent. The other party must not think only he is right and give impression to the world that only he is performing, others are 3rd class workers. The past deafening silence doesn't mean he is correct. More will be exposed in the war... May the force be with us.

    First A and B go over first
    so total time is 4 minutes
    then A come back
    so T=6 mins

    Then C and D go over
    so T= 16+6 = 22
    then B come back
    so T=22+4

    then last B and A go
    so T= 26+4 = 30

    Time Management skill learned:
    1) not to put genius to lead the idiot all the time.
    2) Overuse the genius does not mean most efficient

    There are 80 balls all of them are equal in shape and colour but difference is that, out of 80 balls 79 are of equal weights but one is either heavier or lighter to rest of 79 balls.

    You have been given a balance. How many minimum attempts should be employed to find the odd ball out.

    u see, all problems as presented here are bogged by rules. Who set the rules (management, owner?)? Why the rules are there? Can the rules be changed to provide faster solution?
    Is the rigidness of the rules due to safety, functionality or pure egoistic?
    In the boats case, why can't a boat tow all boats in one time? Or add another boatman.

    hehhee...for CYC sake...

    There is only one boat man because some are busy writing method statement and writing emails. The rest are commanding officers and admirals that should not get their hands dirty.

    Due to restiction imposed by safety manager, it's only safe to tow one boat with another.

    You are the boatman, to think of the best solution on how to get all the boat across so everyone else will (or MAYBE) also get a big fat bonus.

    tadaaa....
