well actually. the riddle itself is well "easy" w.e but look at it in this way. they had to pay 25 all payed 10 and got back 1 for each ( 3 ) and 2 to bartender. so by 10-1 = 9 (cuz they payed less when they got some back..). should be correct rite? now 3x9=27 and 27+2 = 29.. wheres the missing 1 in making it this way?
-did i even make sense ffs :'/ -
