OA is 40%. The cigarette break was extraneous information! Just thought I`d throw you guys a curve ball for once.
Bob can do the job in 5 hours, so he completes 1/5 of the job in 1 hour. So in the 3 hours they both work, Bob does 3*1/5, or 3/5 of the job. Neil does the rest, or 1-3/5 =2/5 or 40% of the job.
