Pull Request: C3 sharaf 473 set of problems 3.17 c

Please Review @Ahmed-Atef @ranaelnagar @Rania-Abdel-Fattah @Ahmed-Moataz @ahmed93 @AhmedOsam 
Issue #473 
Simply this is a seeds based story, where only i added new problems to the database to be used within the website.
There are neither tests needed to be reviewed nor documentation, however a scenario reviewer if you enter the tutor website you won't be able to see these problems anywhere other than the problem bank since they are not assigned to a specific lecturer/ta. And the problem bank is not yet merged to the master, so as soon the problem bank is merged i will tag you again to review.
@fadel1493 you may need to refer to this branch.
