The Missing Dollar
Three men go into a motel. The man behind the desk says the room is $30, so each man pays $10 and they go to their room. Later, the man at the desk realises the room was only $25 and sends the bellboy with $5 change. The bellboy can’t work out how to split $5 between three so gives each man $1 and keeps $2. This means each man has paid $9 (total $27), add the bellboy’s $2 = $29. Where is the missing dollar?
This one really hurts my head. But I know the answer.
(3×10)-5+3+2=30-5+5=30
{3×(10-1)}+2=(3×9)+2=27+2=29
Is it correct??? Don’t laugh if I’m wrong!!
well that clears that up then!
Mariko, your sums are correct. But that doesn’t explain where the missing dollar is though. Where is it?
?????? Give up! Where is it?????
Well the answer is that there isn’t a missing dollar. Because the guys only paid $25 – but the bellboy stole the other two dollars. You should subtract 2 from 27, not add it. But the way the question is worded it makes it hard to understand.
It still hurts my head a bit.
yep. i knew that
