Tricky...

Three men moved to a motel ...The clerk said that it will cost $10 each for a room.Which means $ 30...When the three went away...The clerk found that he took $5 more from them i.e. $( 30-5 )=$25

Now he went to the manager to get rid of this tension...

After hearing the incident Manager replied 'Give me $25,Take $2 for yourself & Distribute $3 between three of them(The three men) '

Now ,The question

Total expense by all three men = $9(10-1)

Which means = 9* 3 =27

Again ,27+2=29 ($2 taken by the clerk)

Now where the $1 gone?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Comments

the misleading calculation presented by the author leads to think that $1 is missing, which actually is not the case.

each spent $9, so in total they together spent $27. now, $27 minus $2 taken by the clerk is $25 which is the amount they paid for the room.

as for the $30 originally paid, they can be obtained again by doing: 25 for the room + 3 for each man + 2 for the clerk.
