Right that blackboard one, its got to be a multiple of 9 of those numbers, and the 2 that arnt correct must be side by side....
So it must be a multiple of an even number, thus all odd numbers are out....
Must be a multiple of either 5 or 10, now it cant end in 5 as above, so must end in 0...
More to come when I can think of some.....

The numbers before the 0 have to be a multiple of 3.

If both 12 and 11 are correct, then the figure would have to be divisible by both of them, ie 132. Ending in 0 that leaves 1320, 1980, 2640, 3300. If all 4 of these options do not fit the criteria, then we can assume that the answer is not divisble by 12 and 11.
1980 is divisible by all numbers in the list bar 8 and 9
thats my answer

Q2 is just a lot of sums. I'd essentially just assign a value to a "part" of wine/water, then count the number of parts of each in the final mixture. Hate those questions, really easy to get confused and screw a number up.
I suspect there's more to Q4 than initially meets the eye so I'll have to try it some time when it's not so late.
1980 / 7 = 282.857143
always helps i continue on my maths. My eyes that means 12 and 11 are wrong.

But 1980 divides by 9 - so you're good
Yeah, just spent ages recalculating, then realised it was a typo first time!
Yeah, exam sniffles are pretty bad. The stuff I hated the most in exams were wobbly tables and creaky chairs.
Had the misfortune of getting both during the same Finance exam in first year. Felt like the longest 3 hours of my life.
