Here is the solution :

Each person's share is $9. So their total amount is $27.

Here come the tricky part. Now we have to add the remaining $1 of each person, ie $3 rather than $2. The reason is that $27 includes $2 of bell boy and we are forced to think that we should add 2 with 27, which is the actual trap.

$27($25 for room rent with $2 of bell boy) + $3 (remaining in their hands) = $30!

You've found the solution, Praveen, thank you!
But I knew there was a trap in the way the question is asked!

I was thinking for the solution this evening with a pen and a paper and fortunately after 5 min I got the solution.

The facts in this riddle are clear: There is an initial $30 charge. It should have been $25, so $5 must be returned and accounted for. $3 is given to the 3 friends, $2 is kept by the bellhop - there you have the $5. The trick to this riddle is that the addition and subtraction are done at the wrong times to misdirect your thinking - and quite successfully for most. Each of the 3 friends did indeed pay $9, not $10, and as far as the friends are concerned, they paid $27 for the night. But we know that the clerk will tell us that they were charged only $25 and when you add the $3 returned with the $2 kept by the bellhop, you come up with $30.

room cost= 25 $
they all payed = 30 $

that's mean every one payed =10 $
bellhop took = 2 $

by devied the 2 $ to 3 guys =
1/3 1/3 1/3 1/3 1/3 1/3 = (1/3 1/3)=2/3 - (1/3 1/3)=2/3 - (1/3 1/3)= 2/3

so the remainder= 28 $

we said the room cost = 25 $ that's mean
first guy payed = 8 + 1/3
second guy payed = 8 + 1/3
third guy payed = 8 + 1/3

total = 24 +3/3 = 24+1 = 25

since the remainder = 3 (every one took 1 $)

to improve that
1/3 + 2/3 = 1
1/3 + 2/3 = 1
1/3 + 2/3 = 1
8+8+8+3=27 $

plus 3 pounds they got back (27+3= 30)

Your example is confusing, but whatever.. The riddle throws you for a loop when it says they each paid $9.00 for the room to equal $27.00 PLUS $2.00 for the bellhop. You have to remember that you already paid that ***! Total cost for the rooom is $25.00 plus $2.00 for the bellhop. Now they have $3.00 left over. They paid $27.00 and keep $3.00 which equals 30 buck-a-roos!
