Post Series: Fun with Maths

Three Kabaddi players from India travelled to New York for a tournament. After winning the tournament, they decided to visit a nearby town. Once in the town, they chose a hotel to stay in. By chance a room with three beds was available at a reasonable rate of $30. They paid at the reception thinking that they would share $10 each. Soon the bellboy at the hotel reached them and returned them $5 saying that the hotel was giving a special discount that weekend on the hotel rent. The three players decided to give the bellboy $2 and divide the remaining $3 amongst themselves.

The Mystery of the Hotel Rent

But, when they calculated their expenses they could not understand the following details:

Each player had originally paid $10 (towards the initial $30). Then each got back $1 which meant that each of them had paid $9 for the room. They then gave the bellboy a tip of $2.

Now, when we calculate, we find that $9 x 3 = $27

When $2 is added to it, it comes out to be $29

So, where has the last dollar disappeared?

Can you help them in figuring out the mystery?

The trick lies in the way this question is phrased.

The total expenses of the three players is $27 which includes the $2 that the bellboy receives.

$3 was returned to them. So $27 is with the Hotel account and $3 is back with the players.

Hence, $27 + $3 = $30

There is no question of the last dollar!
