Re-post from Feb 17, 2010
try again. Maybe some chinese or korean might have just joined ET. Or maybe even some blacks. All nationalities welcome. All eligible for american citizenship and an intro to a life of "debt financing"
cutting the gradient .....
Two roommate wall street traders travel to work on a circular railway. Their office is situated diametrically opposite to their home. In one direction from home to the office it takes 1 hr 20 min., but in the other direction, only 80 min. - why?
------------------------
An ET farmer has 1 5/8 ( one & five-eights) haystacks in one field, and 2 9/27 (two & nine-twentyseventh) haystacks in another field. If he put them together, how many haystacks will he have?
Feel free to use a sliderule
---------------------------
You have 6 identical matchsticks. Make some equilateral triangles. What is the max. # of such triangles you can make?
supercomputers may be used

for 12 -100 yr olds .....
Try this one - if nobody gets it, answer will be posted 1 yr from today. No hints will be given.
Starting from first principles and without the use of logarithmic tables, slide rules, computers, calculators etc., prove that
cot 7.5 degrees = sqrt 2 + sqrt 3 + sqrt 4 + sqrt 6
i.e. cotangent 7.5 degrees = square root of 2 etc.
Renewed for one more year.
More fun for the stupidest people on earth .....
Complete the series shown by filling in the next 5 lines. Anyone who gets it, gets instantly promoted to "duffer" - generally a 75% improvement at ET.
Note the sheer beauty and transcendental-ness - take a break from your overly stupid consumption of TVs, cars and whatnot.
1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876

Only 6 months left to complete 2 years that nobody has been able to solve this.
