The cashier however sees that the bill is only Rs 250 so calls the waiter and gives him Rs 50 for returning the amount to Tom, Dick and Harry. The waiter assumes that it will be extremely difficult for the trio to calculate the maths of splitting Rs 50 amongst themselves, so he keeps Rs 20 with him and returns Rs 10 each to Tom, Dick and Harry. \n\nInitially Tom, Dick and Harry had all contributed Rs 100 each. So after getting back the change of Rs 10, they ended up paying Rs 90 each, Rs 270 in total. The waiter had Rs 20 with him. So, where did Rs 10 vanish from the initial amount?

The trick is how the question is asked. However if you look at it objectively, the three men spent a total of Rs. 270 which includes the Rs. 20 that the waiter kept for himself. So the total is 250 (restaurant bill) + 20 (waiter) + 30 (money that they got back). \nThe question has been asked in such a way so as to trick the reader. You don't have to add the 20 to 270 because the 20 is already included in 270.

The error is in the way the question is stated at the part where you say each man paid $9 for the room.  They didn't.  They paid $8.33 each, but don't know it.  They each paid $.66 in a tip they also don't know about.  That times 3 = 27 and with the $3 of refund = $30.00.

I think thats the same basically but the one i heard was like this:\n\nThree men go into a hotel and share a room and the room will cost 30 dollars, the men go to there room when the person at the desk realizes the room was only 25 dollars,SO HE SENT THE BELLBOY TO THE 3 GUYS' ROOM WITH $5. ON THE WAY THE BELLBOY COULDN'T FIGURE OUT HOW TO SPLIT $5 EVENLY BETWEEN 3 MEN, SO HE GAVE EACH MAN A $1 AND KEPT THE OTHER $2 FOR HIMSELF. THIS MEANT THAT THE 3 MEN EACH PAID $9 FOR THE ROOM, WHICH IS A TOTAL OF $27, ADD THE $2 THAT THE BELLBOY KEPT = $29. WHERE IS THE OTHER DOLLAR?

The men paid $27 (3 x $9).  $2 went to the bellboy and $25 went to the manager for the room.\n\n$27 *minus* $2 = $25\n\nNothing is missing!

Well first of all, she should have enough money to pay for herself. When the check comes and they're about to pay she should ask him of how much does she have to pay for her meal, in 95% he'll offer to pay, she should ask him to pay herself again(with a true voice), if he accepted at this point so he wasn't willing to pay her from the first but if he insisted on that then she lets him do so, and she should after that with a day or two she might buy him a present which he would appreciate much. Having sex at this point isn't a very good reaction coz he will think even by 1% that she's cheap.\nAssume the waiter/waitress was heading towards her with the bill, at that moment she should look in another direction or to drop something and gets down to get it.

each person gets $1 back, so that means  25 + 3 = $28\nand the bellhop keeps $2, and thats $30

you're indeed a filipino!\n\ntry this one...i know the problem is already wrong\nbut this is even better...you'll get the extra dollar!!!!\n\nyou borrow $50 from each of your friend\nbought item worth $97\nyou have $3 left\ngive them $0.50 each\nyou have $2\n\n50 - 0.50 = 49.5\n49.5 x 2 = $99\nyou have the $2 remaining\n\n$99 + $2 ====== $101   TADA!!!!\n\nhehehehe...isn't it genius!!!!

it doesnt matter how much a b and c "spent". they all gave d ten dollars. that equals 30 dollars. person d spends 25 dollars. then he gives 1 dollar back to a b and c. a b and c all have 1 dollar, which equalls 3 total $. person d has $25, plus the 2 he has left=$27, plus the three owned by a b and c=$30.

this is dumb... where did the $9 come from?  Something cost $25 so there was $5 change.  Dad took $2 and so that leaves $3.  Which is $1 for each kid.

You have to bear in mind that the drinks were not actually $27 dollars, it was $25.  Just because you gave them a dollar each back, they ASSUMED it was $27.\nEven though they had paid $27, you still had to pay their bill of $25 which would leave you the $2.....\nthe missing $1, is therefore, not a missing dollar....!

The only problem with the math is that you don't ADD the two dollar tip to the $27; it's already included.  Remember, the $25 room charge plus the $2 tip gives the $27 total payment; the $3 change makes up the rest of the original $30.

ok. there are 3 guys who go on a road trip. they go into the hotel and its $30.00 even for the room. so each guy pays 10.00. (10 x 3 =30)\nwhile they are in the room the checkin girl realizes its only $25.00 for the room. so she grabs 5 one dollar bills and goes up to the room. she realizes that 5 does not divide by 3 evenly. so she taked $2.00 and puts them in her pocket. as she knocks at the door she feels guilty and pulls the $2.00 out of her pocket. they ended up giving her 2 dollars and kept 3. if each guy gets 1 dollar back then instead of 10 they paid 9 each for the room. ( $9 x 3 = 27)\n27 + 2 (tip they gave lady) = $29.00\n\nWHERES THE LAST DOLLAR??????????????

1)    let x be the number of Rs 500\n       so, 200 - x is the number of Rs 200 (because the number of prizes must sum up to 200 to be distributed amongst the 200 persons)\n\n       Rs 500*(number of Rs 500) + Rs 200*(number of Rs 200) = Rs 50000\n      (Rs 500)(x) + (Rs 200)(200-x) = Rs 50000\n       500x + 40000 - 200x = 50000    (just distributed Rs 200)\n       500x - 200x = 50000 - 40000    (40000 was subtracted from both sides of the equation)\n       300x = 10000\n            x = 33.3333 <--- number of Rs 500\n 200 - x = 166.666667 <--- number of Rs 200\nthe answers must be whole numbers... but if you will round it off to the nearest unit digit, there will only be a total of Rs 49900. so, it is not possible for 200 Rs 50000 to exist consisting only of either Rs 500 or Rs 200.\n\n2)   let x be the worth of Bryan's property\n    (Son's share) + (Daughter's share) + (Wife's share) = (total worth of Bryan's property)\n      (1/5)(x) + (1/5)(x) + Rs 288000 = x\n       (2/5)(x) + Rs 288000 = x\n        Rs 288000 = x - (2/5)(x)\n         Rs 288000 = (3/5)(x)     (multiplying both sides of the equation by 5/3)\n               Rs 480000 = x    \n\nso, Bryan's property is worth Rs 480000

Let x be the number of days worked and y be the number of days idle.\nGiven that No. of days worked is 36 ie m =36\nHe gets Rs.58\ni.e 2.50*36-1.50*n = 58\n    1.5n = 32\n => n = 32/1.5 =48 days\n\n\nso in total out of 84 days he worked 36 days and idle for 48 days to get his pay of Rs. 58\n\nThis is the solution to the problem

Well, if the assumption is that the non-alcohol drinkers shouldn't pay for any alcohol, then this is how it works out:\n\nEach person's contribution towad the $3000 is $200.\n\nThe non-alcohol tab should be split among all 15 people - that's $1962, divided by 15.... equals $130.80\n\nThe alcohol tab would be split among the 12 alcohol drinkers... that's $538, divided by 12... equals $44.84.\n\nSo, the three non-alcohol drinkers spent $130.80 of their $200 contribution.  They would be refunded $69.20 each.\n\nThe 12 alcohol drinkers spent $175.64 of their $200 contribution.  They would be refunded $24.36 each.\n\nAfter issuing these refunds, you'll be left with 8 cents.  You can divide this up however you wish.\n\n*** KingYellow and Word Nerd - double check your answers.  You are going to end up refunding 4 cents more than you have available to give back.  Somewhere along the way you rounded off incorrectly.   ***
