# Need Help With This Riddle

3 students purchase a coffee table for the sum of £30 from the local second hand shop paying £10 each. The owner thanks them for the business and promises to deliver it the next day.

The next day he loads the table onto the vehicle and gives the delivery driver £5 to return to the students as "they are good customers". The driver sets off and en-route decides that the students would never know if he bought himself a sandwich out of the £5. He delivers the table and gives the students £3 back "for being good customers"

One says " Thanks that's great, that means we've only paid £9 each for the table". The driver sets off and suddenly has a thought "if the students have paid £9 each, that’s £27 and i spent £2 on a sandwich that's £29 in total".. Where has the other £ gone" ....
Welcome to the forums!

This is a well-known 'riddle' that simply tries to mislead people.
Of course the other pound can't just disappear. The answer is that there is that no reason that what the students paid and what the sandwich costs should equal 30 pounds.
