Three travelers stopped at an inn for supper. The innkeeper could offer
only baked potatoes. While the potatoes were baking, the travelers fell
asleep. Soon, one of them woke up, saw the dish of potatoes, and took a
third of them without waking the others. Later the second one woke up, saw
the dish, and ate a third of the remaining potatoes. Later the third one
did the same. When all three were sleeping once again, the innkeeper
cleared the table and found 8 potatoes left.
How many potatoes were there to start with?
Read Solution (Total 1)
-
- initially let x no. of potatoes are there.
1st traveller=x/3
rem=(x-x/3)=2x/3
2nd trv=(2x/3*1/3).rem=(2x/3-2x/9)=4x/9
3rd trav=4x/27
rem=8x/27=8 i.e. x=27 - 12 years agoHelpfull: Yes(13) No(2)
