Problem 771 in Project Euler asks to find the sum of all positive integers n below 10^6 such that the sum of the proper divisors of n is a perfect square. The proper divisors of a number are all its positive divisors excluding the number itself. This problem involves number theory and requires efficient algorithms to find the proper divisors and check if their sum is a perfect square. **

Amazon typically keeps around 2.5 euros from a 30 euro gift card, which is approximately 8.33% of the total value.

It is not clear what "fit 30" refers to in this context. If it is asking whether a graphics card can fit into a computer case that is 30 centimeters wide, then it would depend on the specific dimensions of the graphics card and the available space in the case. It is important to check the dimensions of both the graphics card and the case to ensure compatibility. If "fit 30" refers to something else, please provide more context for a more accurate answer. **

To determine if graphics card 30 fits, you need to check the dimensions of the graphics card and compare it to the available space in your computer case. Measure the length, width, and height of the graphics card to ensure it will physically fit in the case. Additionally, check the power requirements of the graphics card to ensure your power supply can support it. If the dimensions and power requirements are compatible, then graphics card 30 should fit in your computer. **

As of my knowledge cutoff date in September 2021, it is unlikely to find a new graphics card for 30 euros. Graphics cards are typically priced much higher due to high demand and limited supply. However, you may be able to find older or used graphics cards for around 30 euros from second-hand marketplaces or auctions. Keep in mind that the performance and compatibility of such older or used graphics cards may not meet the requirements of modern applications or games. **
