What number is as much more than 10 is less than one half of what 30 is 10 less than?
The number that 30 is ten less than is 40. Half that is 20. So the question becomes "what number is as much more than 10 is less than 20". This is gobbledygook, but if I rephrase to say "what number is as much more than 10 than 10 is less than 20", then since10 is less than 20 by 10, I guess 20.

What is a number less than 20 and has 3 factors?
4 and 9. Factors of numbers come in pairs which means that every number ought to have an even number of factors. To have an odd number of factors, one factor pair must be a repeated number which means that only square numbers have an odd number of factors. The square numbers less than 20 are 1, 4, 9 & 16 and of these 4 & 9 have 3 factors: 4: 1, 2 & 4 9: 1, 3 & 9
