Here are a Few Interesting Logical Riddles which you can ask your friends on Whatsapp, BBM, We Chat, Lime or any other chat app.

You can pass it on to Whatsapp groups and impress people with your wit.

The solutions are also mentioned after the questions.

**Puzzle 1:**

A guy has two wires of varying thickness, which each burns in 60 minutes. He actually wants to measure 45 mins. How can he measure 45 mins using only these two wires. (he can’t cut the one wire in half because the wires are non-homogeneous and he can’t be sure how long it will burn)

**Puzzle 2:**

Two trains enter a tunnel 200 miles long, traveling at 100 mph at the same time from opposite directions. As soon as they enter the tunnel a supersonic bee flying at 1000 mph starts from one train and heads toward the other one. As soon as it reaches the other one it turns around and heads back toward the first, going back and forth between the trains until the trains collide in a fiery explosion in the middle of the tunnel. How far did the bee travel?

**Puzzle 3:**

There are three jars that are all mislabeled. One contains peanut butter jelly beans, the second contains grape jelly beans and the third has a mix of both (not necessarily mixed in 1:1 ratio). 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 : Mix of peanut butter and grape.

The answers to the above puzzles are as follows;

**Solution 1:**

The guy to start with will burn the first wire at both the ends and the second wire at one end. After half an hour, the first wire burns out completely and at this point of time, the guy will burn the other end of the second wire so now it will take 15 mins more to completely burn off. so total time taken is 30 +15 i.e. 45 mins.

**Solution 2:**

This is a tricky one. At first you would start thinking of solving this problem like this “ok, so i just need to sum up the distances that the bee travels…” but then you quickly realize that its a difficult (but not impossible) summation.

The correct approach to solve this is as follows: The tunnel is 200 miles long. The trains meet in the middle traveling at 100 mph, so it takes them an hour to reach the middle. The bee is traveling 1000 mph for an hour (since its flying the whole time the trains are racing toward one another) – so the answer to this puzzle is that the bee travels 1000 miles.

**Solution 3:**

Only one jelly bean from the Jar 3 (Mix of peanut butter and grape) will do the trick.

The logic here is to realize that every jar is mislabeled. Therefore you know that the peanut butter jelly bean jar is not the peanut butter jelly bean jar and the same goes for the rest.

You also need to realize that it is the jar labeled 3, labelled as the Mix of peanut butter and grape jar, that is your best hope. If you choose a jelly bean out of there, then you will know whether that jar is peanut butter or grape jelly jelly beans. It can’t be the mix jar because i already said that every jar is mislabeled.

Once you know that jar 3 is either peanut butter, or grape jelly, then you know the other jars also. If it is peanut butter, then jar 2 must be mixed because it can’t be grape (as its labeled) and it can’t be peanut butter (that’s jar 3). Hence jar 1 is grape.

If jar 3 is grape, then you know jar 1 must be the mix because it can’t be peanut butter. (as its labeled) and it can’t be grape (that’s jar 3). Hence jar 2 is peanut butter.
