You guys and gals want to solve a problem?

2 students were given this problem. Shilpa was told the shape. Colin was told the color.
The instructor asked the same question to both 3 times.

What color and shape is the prize?

Its the green triangle

Cant be the yellow circle because Colon woupdvd known right away. Likewise it cant be the square or Shilpa wouldve known. You can eliminate from there using deductive reasoning

Okay. If the shape was square, or the color was yellow, one of the people would know in one round. So, we can eliminate the yellow circle or blue square. Then, if the color was blue, after the first round, where the shape guy didn't say anything, the color guy would know it is blue triangle, so we know it isn't blue triangle. Likewise, if the shape was circle, after the first round, if the color guy did not say yellow circle, the shape guy would know it is green circle, so we know that is not the case. Therefore, the only possible answer is green triangle.
