When a system is taken from state 'a' to state 'b' along the path 'acb', it is found that a quantity of heat Q = 200 J is absorbed by the system and a work W = 80 J is done by it. Along the path 'adb', Q = 144 J

In the above question, if the work done on the system along the curved path 'ba' is 52J, heat absorbed is
