Question

There was a jar of cookies on the table. First Ken came along. He was hungry

because he missed lunch, so he ate half the cookies in the jar. Mary came in the
kitchen next. She didn't have dessert at lunch so she ate one third of the cookies
left in the jar. Karen followed her to the cookie jar and she took three fourths of
the remaining cookies. Susan ran into the kitchen, grabbed one cookie from the
jar and ran out again. That left one cookie in the jar. How many were in the jar to
begin with?

Answer 1

There were 24 cookies in the jar at the beginning.

Explanation:

There is 1 cookie left add the one susan took that is two. Two is 1/4 of 8. Eight is 2/3 of 12. Twelve is 1/2 of 24. 24 is the answer. You can also check it by going back.
