AnswersAgain part of "coding" test for non-programmers
- amazon August 10, 2012 in United States
What number is non-standard if standard means all integers.
Answers included 99, -0. 11.2, and -16. Unsure if -0 is an integer. No answer was an option as well.
Edit: that non-standard was not in the original question. I do not recall the question exactly, but it revolved around whether -0 is an integer.| Report Duplicate | Flag | PURGE

AnswersWhich is a true statement?
- amazon August 10, 2012 in United States
if both true, A&B=True
A&B=False if only one false
A^B=True if only one True
Which of these 5 is not true? The all seemed fairly obvious except
1) A&B^C
2) 8&0+0=0
3 others I forgot
One was a math problem without an =
the challenge was not the logic but whether
one can classify an equation with 0=0 or answer 8 as
true or false.
No answer was available.

AnswersWhat is the remainder of normal fraction?
- amazon August 10, 2012 in United States
# = Modulo
Several problems used the # symbol defined as
the remainder 4 / 3 =1
One question asked 3 /4 another 1/2
another had 0/0
You had to know not only modulo but whether it
is usable for a normal fraction.
Please update if you take the test

‘ means not. It converts a character to null in a string but converts the character to 0 in an operation
1=John 2= Jane 3= Does
“’123” = ?
Jane3Does was the closest answer. It seemed wrong because of the 3 in there.
I'm sorry i forgot the other answers, but they were
equally illogical.| Report Duplicate | Flag | PURGE

There are four people who want to cross a bridge; they all begin on the same side. You have 17 minutes to get them all across to the other side. It is night, and they have one flashlight. A maximum of two people can cross the bridge at one time. Any party that crosses, either one or two people, must have the flashlight with them. The flashlight must be walked back and forth; it cannot be thrown, for example. Person 1 takes 1 minute to cross the bridge, person 2 takes 2 minutes, person 3 takes 5 minutes, and person 4 takes 10 minutes. A pair must walk together at the rate of the slower person’s pace. For example, if person 1 and person 4 walk across first, 10 minutes have elapsed when they get to the other side of the bridge. If person 4 returns the flashlight, a total of 20 minutes have passed and you have failed the mission.| Report Duplicate | Flag | PURGE
