Are these online or in the office?
I'm not great with maths, but what I found really helpful, and consequently ended up doing quite well in them, was writing down equations on a piece of paper and keeping it near me.
For instance, a lot of those tests are calculating percentage increases. Have something simple written down which tells you how to calculate the difference. If you need to calculate the percentage increase between A and B, just write down "Percentage increase from A to B = (B-A)/A * 100.
Do a lot of the practice ones and the more you do, you seen similar type of questions coming up. Percentages were very common. Write down anything you think comes up a lot so that as soon as you figure out what it is you need, you can just look at that sheet, input the numbers, and get the answer.
What they often do is try and trip you up with decimal points (millions vs thousands etc.) so keep an eye on that.
I bought a set of practice ones here http://www.assessmentday.co.uk/ and found them helpful.
