Most people don't realize how much power it takes to run a lab full of computers. Computers consume enough power that if you are not careful, you can easily blow a fuse. Calculating how much power is needed for a lab is a simple process, but it can be time consuming if you have to do it again and again. A local group of electricians, the Adept Circuit Makers guild, feels that they have wasted too much time calculating power requirements for computer labs, so they have asked you to write a piece of software to help them with their calculations.
Every computer has a single monitor.
The electrical code requires that each lab must use a fuse rated at least two times the average ampere load for the equipment in that lab. Given these figures, you are to write a program that will read as input the number of computers, the number of printers, and the number of routers. Your program should then calculate and print out the size of the smallest fuse for that lab. Remember that fuses only come in ampere ratings that are multiples of 10 amperes. Computers are evolving at an incredible pace, and savvy business people know that it is important to keep up with the times in order to be successful.
