Thread: Olympic Rings Mathematical Problem

Please view above ^^^^^^

Anyway, if you cannot read what it says here it is:

The 5 Olympic rings cut the plane into 15 pieces (not counting what is outside the circles). Arrange the numbers 1 through 15 in these pieces so that the sum of the numbers inside each ring is 39.

NOTE: THESE ARE NOT THE CLASSIC OLYMPIC RINGS. PLEASE VIEW THE PICTURE BEFORE ANSWERING

Here's one of the solutions (in attachment).

actually, the sum of the numbers in the bottom right ring is 40. this is not a solution

Can someone please post a solution?

see attachment.. this time it's correct

sorry for the mistake in my previous post.

What's your logical approach to solving this problem? I tried using parity to guess how many even and odd numbers each ring will contain.
