Could you pass the 11-plus?

Check here - I got 13/15 - I ended up skipping questions 10 and 11 in order to finish inside the ten minute time limit.

Ok - my brain is clearly cheese this afternoon. What's the answer to 10/11?

10 is 50; 11 is 1.

10 is "a - (b+1)"
11 is "b - 2a"

10. Deduct the second number from the first and take away 1 from the result.

11. Double the first number and deduct it from the second.

D'oh, I was trying to get from the first number to the third, using the middle one.

Of course, that should work, but is probably harder to visualise. I tried to get to the big number from the two middle-sized ones, which seemed easiest.
