There are 3 baskets. one of them have apples, one has oranges only and the other has mixture of apples and oranges. The labels on their baskets always lie. (i.e. if the label says oranges, you are sure that it doesn't have oranges only,it could be a mixture) The task is to pick one basket and pick only one fruit from it and then correctly label all the three baskets.

You've got someone working for you for seven days and a gold bar to pay them. The gold bar is segmented into seven connected pieces. You must give them a piece of gold at the end of every day. If you are only allowed to make two breaks in the gold bar, how do you pay your worker?

I will make the cuts such that i get 1, 3 and 3 pieces from the 7-piece connected bar.

It is an old question..

Pick the box which is labelled "oranges"(incorrectly labelled).
Open it n see----2 scenarios

1. It contains apples. then the box labelled "apples" has both the fruits and the third box has oranges. now change the labels accordingly.

2.It contains both the fruits. then the box labelled "apples" contains oranges and the third one contains oranges. change the labels.

Same can be done if u pick the first box which is labelled "apples"...

I have made only two cuts in the bar.
At positions after the first piece and after the fourth piece.

So after these two cuts u will have 3 bars having 1,3 and 3 pieces respectively...

draw on paper and see.

ya it is correct but how can u determine that there is no oranges from where u pick an apple there is a possibilty for oranages also. u can't see any of baskets so how will u determine it.
