freedom4ever SG

group the balls into 3 groups and name the balls ABCD EFGH IJKL.

compare ABCD with EFGH.

if ABCD = EFGH,

then compare AI with JK.

if AI = JK L is the odd one out

if AI > JK or AI < JK compare J with K.

the rest i not sure how. i only know if the first reading balance.

ChoCoChips SG

oh. no wonder.

at least i got the 1st step correct.

skythewood SG

i post some easier one.

3 guys are buried in the desert to the neck.
they are buried in a row, so guy1 see nothing, guy 2 can see guy 1, guy 3 can see guy 1 and 2
if they shout the colour of their hat, they will be saved.
they know the colour of the hat is either black or white, and that all 3 hats is not the same colour.

who should guess the hat colour?

scenario 1:

guy 3 see guy 1 and guy2 same hat colour

solution: guy 3 shout the answer.

scenario2:

solution: if guy3 never shout, guy 2 knows guy1 and guy2 diff hat colour. guy 2 shout answer.

ChoCoChips SG

freedom4ever SG

maybe i post a question too. this one quite easy.

a mosquito coil can burn for 1 hour. by giving you 2 identical mosquito coils and a lighter, how can u find out a time of 45 mins. you are only allow to use the given items to find the time.

Detached SG

You very ma-fan one.....

Put six balls on each side, remove 3 balls from each side first, then followed by 2 balls if they are still balance, then you know which ball is unbalance.

The key is to keep weighing the unbalance balls, be it 3 on each side or 2 on each side. Remember to keep replacing the balance balls with the unbalance balls and stuff them into Detached's mouth and then continue until you get 1 ball on each side.

Still wrong, exceeds 3 weighing limit.
