The Box of Chocolates Stumper
A decadent box of chocolates adorned the kitchen counter. When Jake saw it, he ate 1/6 of the box. Then along came Joe and he ate 1/5 of what Jake left. Along came Jill who ate 1/4 of the chocolates that remained. Later that day, Jeff ate 1/3 of the remaining chocolates. By the time I got there, I managed to eat 1/2 of what remained. When my sister Sandy came along, only 4 chocolates remained in the box.
Just how many chocolates did Jake manage to eat? The solution follows.02of 02
Solution to the Box of Chocolates
The answer to the box of chocolates' math stumper is: 4
Before Jake ate any of the chocolates, there were 24. He ate 1/6 of 24, which means he ate 4 and left 20. Joe ate 1/5 of 20, which means he ate 4, which left 16. Jill ate 1/4, meaning she ate 4, which left 12. Then Jeff ate 1/3 of 12, which means he ate 4, leaving 8. Then I came and ate 1/2 of the 8 remaining, which means I ate 4 and left 4.
