I had an interview for a plumbing course which included a 100 multiple choice question maths test and was given a calculator.
There was three questions on area and it gave the formula Pi/r/squared;
1. The area of a rectangle, which at the time I did not know how to do with pen and paper, always been bad at maths, but it's easy on a calculator. Answer was one of those given.
2. The area of a circle, but did not understand the formula (at that time). The diameter was 1m (I think) so allowing for corners you loose about a quater if it was 1m square to 1m diameter circle. 2 answers way too low and 2 were 7000 odd square cm's, 10,000 in 1 square metre. So took a guess.
3. Add both areas together, but the answer I had did not match any of the answers available, I knew the rectangle was correct but wasn't sure of the circle, so changed it for the other one and added them together. This matched one of the possible answers.
The interviewer had to pop out for a bit and I did not know he had the answers in his file and did not sneak a look.
He checked them when came back and said I had got all 100 correct and asked if I had looked, "No".
If I had to think for myself I would have got 2 wrong and if I didn't have a calculator it would have been all three.
There were other questions where I was able to use logic or a calculator to answer, and should not haved scored as highly.
