In a magic triangle, each of the six whole numbers 10-15 is placed in one of the circles so that the sum, S, of the three numbers on each side of the triangle is the same. What is the alrgest possible vaulve of S?
I did it as follows:
15 10 13
Each side adds up to 38
Actually, the correct answer is 40 according to AOPS: https://artofproblemsolving.com/wiki/index.php/1985_AJHSME_Problems/Problem_24
thank u so much!
I believe you have read the answer on that site incorrectly.
That site does not claim the answer to be 40
yes, its 39
It was good that guest2 found the site and good that guest1 looked for his/her own solution.
Thanks to both of you.
Maybe you are the same guest lol
