Niladri, yes, i can provide both solution and answer. But these are for your practice. Try them, write answer in comment box here. I will check your answer and tell you whether your answer is correct or not. In case of wrong answer, i will help you to make you to understand that concept. But try this first by yourself. Hope you get this.

Bhavika, 3+3i is not satisfying the question because magnitude of 3+3i+3-i is not 4.

point of intersection of line x=y and circle having centre at (-3,1) and radius 4 unit. because arg(z)=pi/4 means ray x=y from origin.
