For HCF to be 30, the two numbers must be multiples of 30 i.e. their sum also MUST be divisible by 30 but 225 is not divisible by 30

HENCE, YOUR QUESTION IS INCORRECT

If you are preparing for GMAT then the practice material that includes this question is suicidal.

I hope that helps!!!

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
