#323551 Elevators problem

Posted by ujjagrawal on 31 July 2012 - 10:35 AM

Most of the people, I understand, must not be happy with the logic by which the elevators on their building works. This is an opportunity for you to work on a logic that should be efficient, fair and a practical one.

There is a 12 floors building (excluding ground level) with 2 elevators. Can you work out what should be the ideal position for the two elevators (in terms of floor numbers), while they are not in use i.e. idle. Assume equal probability of getting calls from all 12 floors.

#320059 Which Chair you will choose ?

Posted by ujjagrawal on 25 June 2012 - 05:19 AM

Prof. Sushi Rama gives out only one A+ each year in her course on Logic. This year, you and two other students got 100 on all the exams, and you REALLY want that A+. The professor says that she will give the 3 of you a test to determine the winner.

There are 3 chairs in her office. After lunch each of you will sit in one of the chairs, and then she will paste two stamps on your forehead. She shows you the 4 white and 4 black stamps that she has. You will be able to see the stamps on the other two students' foreheads, but not your own, or the two leftover stamps. Then she will ask the student in the first chair to tell what color stamps are on his or her forehead. If the student cannot logically deduce the colors, she will move on to the second chair, then the third chair. If that does not decide the issue, she will continue around the circle of chairs until one of you gives the correct response, with correct reasoning, based on the stamps that are visible and the other students' answers.

After lunch you are the first to arrive at the professor's office. Which chair do you choose and why?

#318215 Classic - Ant and Honey problem

Posted by ujjagrawal on 12 June 2012 - 11:51 AM


In a rectangular box, with length 30 inches and height and width 12 inches, an ant is located on the middle of one side 1 inch from the bottom of the box.


There is a drop of honey at the opposite side of the box, on the middle of one side, 1 inch from the top.


What is the shortest distance the ant would need to crawl to get the honey?


Here is a picture that illustrates the position of the ant and the honey.
