A better deal (Posted on 2002-06-21) Difficulty: 2 of 5
Yoric the worker came to a fair looking for a job.

There, Arley, an artisan, offered him the following terms:

"I wil pay you once every 67 days, one gold coin for a day of work, minus five coins for upkeep - a total of 62 coins in all!"

Suddenly a competing artisan named Bentley interrupted:

"Don't work for Arley, come work for me instead. I will also give you one coin a day, minus five for upkeep, but I will pay you every 57 days instead of 67. That's right, stick with me, and you'll get your 52 coins a whole ten days faster!"

Even though he wasn't very good at math, Yoric was a smart fellow and quickly figured out who was offering a better deal. Can you do it without using a calculator or performing complex fractional arithmetics?

Solution Kinda ez | Comment 4 of 14 |
both artists were keeping 5 for upkeep, but the first one is keeping 5 for every 67, so the worker was loosing 7.4% of the days he worked, but for the second one, he was loosing 5 coins for every 57 days, that means he is loosing 8.7% of the days he worked, even tho the worker was offered to be paid faster, he was being paid less, unless the worker needed money quick, he should work for the first guy

maybe i got this wrong cuz i didn't give it much thought, but i'm pretty sure it's right
