A two digit number when read from left to right, is 4.5 times less than the same number read from right to left.

6-9=-3
9-10=-1
40-50=-10

-3+-1=-4
-4-(-10)=6
ooops.......my eraser broke

Using mostly Roman Numerals

SIX - 9 ( IX) = S
9(IX)-10(X) = I
40(XL)- 50(L)= X

Answer SIX

Here is a question that is the simplest of math.

Three men agree to rent 1 room for $30.00.
Each pay $10.00 a piece to the hotel manager and go to there room.
The manager thinks $30.00 is to much to pay for 1 room so he tells the bellhop to take $5.00 back to the 3 men but on the way up to the room the bellhop figures he can't split $5.00 3 ways.So what he did was he gave $1.00 back to each and he would keep the other $2.00.

So here is the thing.
If the 3 men got back a dollar that made them pay $9.00 a piece.
3 X 9 = 27 plus to $2.00 the bellhop kept = 29.
Where did the other dollar go?

The trick is in the wording. Out of the initial 30;

The manager kept 25.
The bellhop kept 2.
The three men each received back 1, total refund of 3.

25 + 2 + 3 =30.
