Well, this forum contains quite a few of you smart, engineering types. So break out your slide rules.
The following story problem is just simple math. Not calculus, not algebra, just arithmetic. Yet can be surprisingly tricky....
To make the numbers in the story low, just pretend this took place 50 years ago or so and the prices are reasonable.
Three men are travelling together on business. They check into a hotel and get three separate rooms. The bill comes to $30. Each man pays $10 and they go to their rooms.
The desk clerk then realizes he made an error. The total should have been $25 rather than $30. So he gives the bellboy $5 and tells him to give the men their change.
The bellboy thinks to himself, wait, I can't split this $5 evenly between the three guys, and they should have given me a tip anyway. So he keeps $2 and gives each of the three men $1 back.
The men have now paid $9 each. 3 x $9 = $27. Plus the $2 the bellboy kept. Now comes to $29. But we started out with $30.
Where is the missing $1 ?
Don't want to spoil the fun by giving the answer now. So I'll come back with it in a day or so if you are stumped.
