Hotter and hotter (Posted on 2010-02-08) Difficulty: 2 of 5
Today is Saturday. For the last 5 days, Monday to Friday, the temperatures were rising, i.e. each day was hotter than the previous one. The product of the 5 values (Centigrade degrees, rounded to the closest integer) is 12. What are the five temperatures?

(In reply to re: Indecision by Ady TZIDON)

During review I did question this.  Other than the example in my prior comment I had played with possibilities where decimal values did exactly equate to 12 (hence no rounding).

Another reviewer contended, as has Justin  that " Technically, if the parentheses were describing the product, it would be (Centigrade degrees)^5,..." so as to have a unique solution.

Now that is interesting.  I am regularly confronted with formats of which I had never been presented.  Is the format " (Centigrade degrees)^5  " standard anywhere, or is it his way of trying to emphasise the point?  To me that notation says to raise something to the power of 5.

Ady, thank you.  I do feel some comfort in my first thoughts.
