 ▼ Don Shepherd Posting Freak Posts: 1,392 Threads: 142 Joined: Jun 2007 08-15-2011, 12:05 AM I graduated from high school in 1968 and enrolled in a computer programming school called ECPI (Electronic Computer Programming Institute). To get into that school, I had to take a "Data Processing Aptitude Test." One of the questions on that test was: Quote:In a certain company, 3/5 of the employees can type, 1/4 can take shorthand, and 1/5 can do both. What percentage can neither type nor take shorthand? It was a multiple-choice question, with 5 possible answers. I won't list the possible answers. Disregarding the fact that being able to answer this question has almost no bearing on being able to succeed in "data processing," what is the answer? I didn't know it in 1968, and I'm not all that sure I know it in 2011. I suspect that even if you scored zero on the aptitude test, they would still take your money and enroll you. ▼ Paul Dale Posting Freak Posts: 3,229 Threads: 42 Joined: Jul 2006 08-15-2011, 12:22 AM 1 - (3/5 + 1/4 - 1/5) = 1 - 0.65 = 0.35 = 35%. Minus 1/5 because both the 3/5 and 1/4 included it already and we wouldn't want to double count it. - Pauli robert rozee Member Posts: 170 Threads: 7 Joined: Apr 2009 08-15-2011, 01:55 AM Quote: In a certain company, 3/5 of the employees can type, 1/4 can take shorthand, and 1/5 can do both. What percentage can neither type nor take shorthand? my answer would be 35% (or 7/20). (3/5) - (1/5) can only type = 2/5 1/4 can at least take shorthand, and some of these may also be able to type (2/5) + (1/4) = 13/20 can either type, or take shorthand, or both. the remainder (7/20) can do neither. my reasoning is that in conversational english the assertion "60% of our staff can type" would always include those staff who can both type and do other things. similarly for shorthand.

They gave each applicant a very long test that included word problems and various logic problems. The test had to be completed in a very short time. They wanted to see how fast you could analyze the problems and come up with an answer. Logic problems actually made a lot sense, since the copiers in those days were controlled by relays, a lot like the early relay computers. I didn't get the job - it came down to me and one other person. Overall, I scored higher, but they gave the job to the other guy since "I was single and he was married with kids, and needed the job more than I did." Believe it or not, that was exactly what I was told when I was turned down for the position.

I don't know if that is illegal today, but it seems like it should be.
