[2020] IMS SIMCAT 16 Self-Proctored (6th Nov - 10th Nov)

I beg all to help me with this. How do we solve such questions? I got the answer as 4 but it is wrong. HELP PLS

HOW MANY INTEGER SOLUTIONS TO x^2+y^2 = Z^2+3 EXIST? 

VARC - 28 (21A/11C) --> Need to stay consistent.


DILR - 26 (13A/9C) --> :( Accuracy drop + a set less


QA - 27 (9A/9C) --> 4-5 Qs less


OA - 81 (43A / 29C) --> Let's keep on
