Riddle about Weight Loss Pills


As we see, the previous brainteaser was pretty difficult. This is why the one we are publishing today is easier. Try to solve it. A chubby woman decided to lose weight and went to a doctor. The doctor gave her 4 pills of two different types (2 pills of each) which look exactly the same and warned that taking more than one pill of either type would make her even bigger while missing prescribed dose of two pills at a time would make her very skinny. She is supposed to take one pill of each type in 2 days at 12:00 p.m. sharp to achieve desired results. Unfortunately, the woman confused her weight loss pills and can’t distinguish among them. Help her figure out the way how to take pills now to get desired weight!

Weight Loss Pills

Please, if you want to solve the riddle yourself, be careful and do not read the comments on this brainteaser, there can be some who already wrote the solution there. We will publish the answer in the next brain game. You are always welcome to ask questions about the task, in case something is not clear. But sorry, don’t ask leading questions.

The answer to the previous riddle about the Prisoner Princess is: the Princess asked two simple questions to one of the guards.

  • Are you the “cunning fellow”?
  • (Pointing at any of the doors) Does this door open to freedom?

Well done, Thomas! Now try this one.

  1. The answer given requires some convoluted logic to interpret. If you make up a spreadsheet you will find the only correct answers to the questions to find the freedom door are either “No followed by Yes” or “Yes followed by No”. I still believe that a single relatively simple hypothetical question where the answer is either “Yes” of “No” is far more elegant. “Ockham’s Razor” if you will.
    Regards to all,

  2. I failed to mention that if you get “Yes followed by Yes’ or “No followed by No” don’t use that door.

  3. Cut the 4 pills to the half and first day you take de first 4 halfs and the other day the rest of them. In that way you can asure that is taken one full pill of each type each day.
