A challenging activity for students aiming for high grades. Nice to see everything mixed up together!<br />
Would be even better if answers were provided. Here are mine:<br />
a = 90, b = 58, c = 124, d = 34, e = 56, f = 26, g = 26, h=68, i = 76.

Thank you very much. From #14 I've included the answers. I'll get round to the others later. I hope the series of puzzles have been of some use to your students.
