A sample of an ideal gas is taken through a cyclic process ABCA where process AB is isochoric. It absorbs 60 J of heat during AB and rejects 80 J of heat during CA. No heat is exchanged during process BC. Work of 40 J is done on the gas during BC. If the internal energy of the gas at A is 1450 J, what is the work done by the gas during process CA?
