\$10+\$10+\$10=\$29? Who can solve this?

Try to solve this...

There were three guys at a bar, and they had to pay \$30, so they paid \$10 each..

so \$10+\$10+\$10 = \$30

But hey... there was a mistake, they had to pay \$25 instead of \$30 actually, so they got five \$1 coins back and they leave a \$2 tip.

So here's the thing: Everyone payed \$10, minus the \$1 they got back, it's \$9 each, so \$9x3 = \$27 + the \$2 tip it's = \$29, but in fact they payed \$30... so where's the missing \$1?

Solve it and you might just get that \$1.

I finally found the missing \$, the poster swallowed the coin and not survived the operation to retrived it. RIP

total sum paid for drink = \$30

cost of drink = \$25

therefore amount left = total sum paid for drink-cost of drinksamount left

= \$30-\$25

= \$5

from the \$5. \$2 tip was given to the cashier.

therefore 3\$ is left and this amount is shared amonge the three guys.

the total amount paid in the bar is now =cost of drink (\$25)+ tip(\$2)

= \$27.

amount paid by each of them = total amount spent in the bar/number of guys

= 27/3

= \$9

therefore each of them paid \$9 for the cost of drink and tip. and still have \$1 each in their pocket.

THERE IS NO MISSING \$1.

.Heres the thing.They paid \$10 each,dats \$30.But the actuall money meant 2 be paid was \$25 so the bartender returns \$5cions and they tipped him \$2 now they're left with \$3 change.The \$25 paid divided by three is 8.333333,so they paid \$8.333333 each.This multIplied by the three of them plus the \$3 change and the \$2 tip is \$30.So there is no missing \$1.

You wey sabi, Answer d question

Fairly simple, if you check the amount paid it would be \$27- initial payment of \$10 each amounting to \$30,but remember they have \$1 back each which leaves \$9 each amounting to \$27.Therefore the total amount paid is \$27, \$25 for the drink and \$2 for the tip.There is no missing \$\$\$ and you can take that to the bank.

If I don't make mistake, He be like say na you pick that one \$ and now you want to repent and pay am back

that is the stupidest thing iv ever heard

There is solution since they got \$5 back in coins ,so they all ve \$1 each and \$2 for tips so apparently they ve got noting missing

They all went home with \$1 each nd left \$2 for tips.

\$3each+\$2tips=\$5change+\$25bill=\$30

so noting is missing

Good job Jboy,

Oya Mamba give am the calculator (price sticker of \$25 inclusive)

here is the answer if \$1 is refunded so that each gave out \$9 it would be very wrong after multiplying by 3 to then add it 2 d \$2 it should be added to d \$3 that was given out.

@Mamba, mind u u said they paid the 30 TOGETHER and not seperatly(even though they had to contribute that), so the 25 was returned for them all, they never paid 9 EACH, so taking the 25 from the initial 30,they were paid back 5,out of which they shared 1 each and gave 2 to the waiter, so if u think they paid 9 EACH then u wuld be looking for the remaining one till Jesus comes. And how do u xpect them to share 5 equally amongst 3?

So here's the thing: Everyone payed \$10, minus the \$5 they got back, it's \$25 paid for the meal, meaning \$8.33 each, so \$8.33x3 = \$25 + \$5 (\$2 tip and \$3 shared) = \$30. So, no missing \$1?

the question doesn't conform to the rule of mathmatics!!!

in mathematics, subtraction and division are non associative and commutative while multiplication and addition are both commutative and associative.

in other words, using the simple examples below we can see y we cant lump up subtraction and addition without defining our parameters well enough. same for division and multiplcation.

{1} 2+(3+4) = (2+3)+4

but

{2} 2-(3+4) =/= (2+3)- 4

or 2*(3*4) = (2*3)*4

but

2/(3*4) =/= (2*3)/4

the question is just a silly trick we use to play on innocent friends way back then in high school,

the \$1 is missing in the so called tricky nature of the question, but in real mathematically equation the question cant fly- meaning the question itself is wrong.

The drink cost \$25 NOT \$30 plus \$2 to the waiter (25+2=27). This is a logic problem and you are all confusing yourselfs with the \$30 and \$30 doesn't belong in the answer anywhere after the people get there \$1 back the \$30 becomes \$27, 3x9=27 thats it bill is paid, \$25 for the meal and \$2 to the waiter YOU CAN'T ADD THE WAITERS \$2 back on the bill IT'S PAID!!!!

look at this guy lol

we got einstein in here lol

i dont get it. was that a joke?

This is simple logic problem here is my solution The three guys paid \$30.00 but it was actually \$25.00. So they got there 5 X \$1 coins back (\$5.00) and get \$1.00 each that is \$28.00 (\$25.00 + \$3.00=\$28.00) plus the \$2.00 tip which is \$30.00

Mamba,this suspence is too long.Why not give us the answer to the question or you don't know the answer?

0
Newbie

Thank you matrix, you got that right. Mamba was just trying to confuse us, they paid \$25 not \$27. Meaning that it is possible that not everyone paid in the same proportion, Not to use decimals, try this proportion, 9+8+8=25 plus the \$2 tip. If you add every thing together, it means they actually spent \$27 and not \$30 or \$29 from Mamba's calculation. But it is also possible that they funded the bill ( tip inclusive) in the ratio 1:1:1, 1.e they all had to spend \$9 each.

Newbie

The first thing to understand is that they did not pay 9 bucks each. What they paid was 25/3=8.3333, so they had 5 bucks left of which 2 bucks was given to the bar man as tip, and 1 buck was given to each contributor.

They spent all the \$30. so no \$ is missing.

Mamba,the puzzles says they got five \$i coin which is \$5.There is no missins \$ then if there is it should be with you

I have decided to increase the prize, I'll give anybody that can solve it a calculator that's worth \$25 (absolutely free)

Newbie

There's no missing \$1.

You take the \$2 tip out of the \$27 they all paid (just like olaide said) and u have \$25 which is what they paid for the drinks. The trick is take out the \$2 and not add. Or mamba, u don't even know the answer?

0
Newbie

Yeah I got it.THEY ALL PAID \$30 AND GOT \$5 BACK COS THEY WERE SUPPOSE TO PAY \$25.Just becase the attendant was faithful decided to tip him \$2

meaning     \$30-\$25=\$5-\$2(tip)=\$3    they shared the \$3 left \$1 each.No \$ was left and there was no missing \$.They were friends. Am I right? tell me now

The missing \$1 should be with you
