KarishmaB i get that but if we really think about it, your example says 'complete'. if i say i need exactly 10 mins to complete enough work, then it doesnt rule out the possibility that at 9.99 mins too i can complete enough work because lets say, the minimum time required in this case is 8 mins so any time >8 will also beenough



[quote="KarishmaB"][quote="Elite097"]KarishmaB thanks although i do not quite see how we can confidently say that if he has worked for <5 hours, say 4.8 hours, then he has not earned enough. At exact 5 hours, he has definitely earned enough (100 rs) and jacket costs say 80 rs , but that doesnt rule out the case that at 4.9 hours he hasnt earned enough (99 rs). I have just taken random numbers to present my case although i know we d use proportionality rule to calculate this. Main point is that he could have earned enough even at <5 hours. We just dont know that and hence we dont know if he has earned exactlyenough or not
