Bags of Candies
Math brain teasers require computations to solve.

 I think the answer is wrong. I'm sorry but I get 79. What am I doing wrong? Email me at zembobo@yahoo.com
[84+84+84+84+(avg4)]\5=avg
336+avg4=5avg
332+avg=5avg
332=5avgavg
332=4avg
avg=83 therefore, 5 less than that is 79.

 Ya, I'm sure of it now. The answer is definitly 79. Email me if you can't figure out why or if you don't know how to properly to averages. Double check your answers before you post them. zembobo@yahoo.com

 Ok. Last post. Someone emailed and said that there are two ways to look at the problem. With that in mind, it could be either 16 (not 17) or 79. Sorry 'bout that everyone.

 Very easy. Since the one bag has four less than the average, then the four bags must have four more than the average, making the answer (844)/4  4 = 16.

 Say they all had 20 then that would be 100 candles. But if bag 5 has 4 less making sixteen then those 4 are redistributed to the other 4 bags making 84. Works for me! Good teaser.
