You have three jars that are all mislabeled. One contains peanut butter jelly beans, another grape jelly jelly beans and the third has a mix of both (not necessarily half-half mix). How many jelly beans would you have to pull out and out of which jars, to find out how to fix the labels on the jars?
Labels on jars are as follows
Jar 1 : Peanut butter
Jar 2 : Grape
Jar 3 : P.b. / Grape

You just need to open any of the jelly beans jars (Ans is not just p.b./grape jar). If you open either of Jar1 or Jar2, even then you will be able to label the jars correct. So the correct ANSWER is any of the one jar needs to be opened.
Example if Jar 1 is opened:
Jar one will surely not contain p.b, so it could contain either grape or mix jelly beans.
a. If Jar 1 contains grape jelly bean, then jar 2 will contain mix jelly beans (as Jar 3 can’t have mix jelly beans in it, due to mislabeling) and jar 3 will contain peanut jelly beans
b. If Jar 1 contains mix jelly bean, then jar 3 will contain grapes jelly
beans (as Jar 2 can’t have grapes jelly beans in it, due to mislabeling)
and jar 2 will contain peanut jelly beans
Similarly, it can be explained IF JAR 2 IS OPENED.

NICE One 🙂
