140
The only one I struggled with was:
7. John likes 400 but not 300; he likes 100 but not 99; he likes 2500 but not 2400. Which does he like?
a) 900
b) 1000
c) 1100
d) 1200
Can anyone explain this one to me? I ran through all the mathematical possiblities I could think of, and I know there's an easy answer, and it's driving me nuts. I know it's either b) or c), but don't know which one.
