it was in some practice paper we were given.
what im confused at is wether to use Ihusers method or logs?
oh and @captain, ive got a few papers to go through so im sure this thread will come in handy ... oh and +1
how come the answer booklet says 47.8? is it a typo or has it some how being rounded very differently lol?
ive done some other questions today but ive spotted some tough ones which i might post later.
how did you manage that. its pretty obvious it cant be 200 as that would give a pretty big number, well bigger than 200 anyway
lol, anyway ill get some more qu's up tonight. you can all suffer my pain
oh and if anyone could clarify the right method for the first question that would be great. wood's way looks right but why is it a different answer? it is just a typo on my answer sheet then?
