In this problem we have to try the combinations of q1 and t1. Q2 = 90J and t2= 300k (given) So let's first try with the first combination where t1 is 200k In attachment I have solved the equation so we get q1 as 60J. This is the only combination that gives the correct value as all the other combination for q1 and t1 does not match Hence correct answer is option (a) transfer 60J and sink at 200K Thank you
