Jan Ashbaugh, But it's 1 minus that no.

Isabel Weinberg, I do not know what you answered but the quoted answer is incorrect or the statement of the question is incorrect.

Jan Ashbaugh, I agree 3 different numbers would result in 18 being the answer. Just 3 positive integers results in an answer of 19. That is 1 +1+19 =21 /3 =7

Basic math and logic. 6/6

Jan Ashbaugh, It was 1 - 0.00001. All the choices are subtractions from 1.

Math whiz. For Q 2 unless it is mentioned as three different positive integers, the highest number shall be 19. Question setter either you correct your statement or correct the answer.

For #2 they should have said three different numbers. And sorry but 1.00001>1.01?? I think not!

Robert Slykhuis, YOU ARE RIGHT !!! The question needs to refrase - and look like this: Three DIFFERENT positive integers have a mean of 7. What is the largest possible integer that could be one of them?

6 / 6. Congratulations Einstein - you're a mathematics whiz! All quite straightforward.

I only do metric in whisky bottles

Louise Orrock, me too! I don't see why it couldn't be 19

Robert Slykhuis, I also believe 19 is the right answer

5/6. Annoyed with myself that I got the "mean" question wrong. Interesting quiz. Never had questions like this when I was at school 60+ years ago!

Robert Samuelson, I'm American and it's not foreign to me. Try to think globally and accept differences.

Craig Story, The answer is correct as given.
