A number is between 300 & 400. If it is divided by 2, remainder is 1. If it is divided by 4, 6, or 8, remainder is 3. If it is divided by 10, remainder is 5. If it is divided by 3, 5, 7, or 9, remainder is 0. What is the number?

Coincidently, It is the only number fully divisible by 9 in that range.

If it is divided by 10, remainder is 5 so the last digit is 5. If it is divided by 4, remainder is 3,so it is 315 335 355 375 or 395 If it is divided by 9, remainder is 0 so it is 315

The question is swamping you with words that look like information which will needs to be used, but in fact are junk which tell you nothing new.
When it tells you that the number divided by 10 leaves a remainder 5, what can you work out FROM THAT about the remainder when it is divided by 5, or by 2? Yes, what you can work out is that 5 leaves 0 and 2 leaves 1, the same as what they are telling you elsewhere in the question. What a rotten trick. Several other things they pretend to tell you are like this too.
Don't worry if you can't handle this problem. It needs a cut-through-the-jungle skill that isn't the same as mathematical skill.
