Glass Transformation

Step 1 : Pick the 5th Glass of water and pour the water in 2nd glass.
Step 2 : Keep the glass back and it's done.

You have just moved 1 glass.

The answer would have to be determined by the verb "move". To pick the 5th glass up and pour it into the 2nd glass and then set it back down into the 5th position, you did not "move" the glass... It remained in position 5.

Take the $5^{th}$ glass, pour contents in $2^{nd}$ glass, place back the $5^{th}$ glass.

Alternatively, take the $5^{th}$ glass, drink contents, place back the $5^{th}$ glass, pour water onto the $2^{nd}$ glass. Yes, this is a joke to break the monotony of solutions.

There needs to be a voting system to take out problematic questions such as this one. The vague wording makes the answer very difficulty to logically deduce. First I said 2, assuming that the water could not be transferred. I then said zero, because if the water can be transferred, why not just use a straw to suck the water out and spit it into the other glass? Unfortunately, by clarifying rules to ensure that 1 is the only valid answer, you would also giveaway the "thinking outside the box" aspect of this question. That makes this question extremely problematic.

The correct answer is 2. How could it be 1? If it's anything like Dilroop Singh said, then just siphon the water however you want it, and let the correct answer be 0, I mean, it's not forbidden by the description to exchange water as well as using any equipment to siphon the water out, right? There is apparently no moderators here. And while the questions have no credibility, you dare to tell people if they're correct and tell them "oh it's okay, only how many percentage of people get this right". So ironic especially in the logic section.

There is nothing wrong with this question.

It does not say you have to move, only pick up, the glasses. It says you are not allowed to slide. It does not say you cannot pour.....It asks how many you have to pick up.

All you have to do is pick up the 5th glass (2nd from right), pour the contents into the 2nd glass (from left), and put the glass back down in it's original position.....which means you only have to pick up one glass.

Therefore the answer is 1.

he he ,i got it from adaalat. just pick the 5th glass and pour the water in 2nd glass.just only 1 move.

The question should say instead: "What is the least number of glasses you need to TOUCH in order to get the solution?"

How did people fail this??? Pour cup 5 into cup 2 (counting from left to right)

The problem gets simple when they allow you to pour water from one glass to another.

Just take the 5th (second last glass) and pour it into your second glass (which is empty). Put the fifth glass back where it was, and now you have every other glass filled and only touched one cup.

Its so simple. I got this from the aha! book. Just pour the contents from glass 5 into glass 2.

I move only the 5th glass.

Use the glass in the middle (filled with water) to pour the water to the second glass.

Take the second last glass and pour the water in the second glass.Easy

i would take the bottom glass and pour the water from it into the middle glass

From scenario 1, take the 2nd glass with water and pour the water into the 2nd glass with no water.

just pour glass 5 into glasss 2

Pick up the 5th glass (from left) and pour the water into 2nd one. Then keep it back in its original (5th)position.

Pour the water from the 2nd right glass into the 2nd left one.

The 5th glass pour to the 2nd one

Pick up 5th glass then pour it into 2nd glass. Thus the answer is 1

pick up cup n pour

You pour the middle full glass in the the middle empty glass

the solution is one . answer : pick up 5th glass and pour it into 2nd

These kind of questions aren't why I come to the site, if I wanted questions that are just intentionally misleading and worded vaguely to try and fool people I would go to Facebook. Implement a voting system for questions that are submitted like this so we can avoid these kinds of bar questions.

Pick up the 5th glass and pour its water in the 2nd glass and put the glass back. We only have touched 1 glass

So easy. Pour the water from the 5th glass unto the 2nd glass.
put the 5th glass back. moved one glass and done.

In my eyes, this answer for this is wrong as this problem is stated and its impossible to do it by these directions without picking up and swapping 2 cups. I think it's cheating to pour it out of one glass to another. It says you can only use your hands to pick up the cups and to pour something is more than just picking it up. I know in the notes it says you can pour but If we are allowed to manipulate the situation however we want like this, then the answer is 0 because you don't have to pick up any glasses to get it in that order. Using only my hands I could pick up a syringe and suck the water out of one cup into another actually never picking up a cup. I could put a string in the fifth cup and open my windows to let the water freeze pulling the water out and moving it to the second spot. There are multiple ways of doing it and still upholding the rules as stated. So no matter what, this answer for this is wrong in my eyes. Questions this vaque are left up to too much interpretation and can never have one absolute answer. When it is left up to a person to use his own imagination to solve a problem, things can get very far off from the intended problem the way the author meant it to be. Even though to give too many hints or notes would ultimately be giving the solution and no problem to solve, there has to be clearer stated set of rules.

You pour the fifth glass into the second one thus only picking up one glass.

Pick a second left glass and pour the second left glass

Pick up the second last glass of first row.Pour the water in second and keep the glass again.

drink the water from the 5th glass, put back the 5th glass, spit out the water into the 2nd glass, and your'e

My first answer is 2, but since I wondered that nobody told me that pouring isn't allowed, I tried 1 next...

Who knew that you could just pour the water to another glass?

2 if you don't want to spill any, 1 if you know how to be careful enough.

using the same logic to move 1 glass (IE the water doesnt have to stay in the glass.) you could also move 0 glasses

remove water from 5th glass via vaccuum / straw into container, then pour water from container into 2nd glass

the number of glasses is two. the number of switches is 1. 1 switch = 2 glasses as you cannot switch one glass for itself. You wrote the question wrong.

The answer should be 2 not 1 because we exchange position of 1 full glass and 1 empty glass?

You have to switch the 5th and the second glass. But you actually move 2 glasses! The right answer is however 1.

How to solve it is simple. There are three filled and three unfilled. Two are in the same position as the other, so you only need to move 1 glass, and put it back, and you have the same. For similar problems, let x be glasses filled in the correct position, and y be total filled. y-x. It's that simple to solve these kind of questions. Unless I'm wrong, this should work for any amount of glasses with filled cups in this format.

I do not agree. This question has two answers
