IQ Questions
While I was in the Company Office, I was given two IQ questions. One was from Srgnt P and the other from a fellow OOT, J.
These are the questions...quite hard I should say. Hope that you guys out there will be able to help me solve these questions.
1. There are 12 balls. One of them is an oddball...it's either lighter or heavier than the rest of the 11 balls. Using a scale three times, how do you which ball is the oddball and whether is it lighter or heavier than the rest.
The scale in this question refers to a device that has two sides...the left and the right. You put things on both sides and see which side goes up or down. The side that goes down is heavier while the side that goes up is lighter. There are no readings or whatsoever.
2. How do you get 100 using four 9s. You can add, subtract, multiply, divide to get 100. Play around with the four 9s using the mathematical operators to get 100.
Hard aren't they?
