An ideal gas is taken round a cyclic thermodynamic process $ABCA$ as shown in the given figure. If the internal energy of the gas at point $A$ is assumed zero while at $B$ it is $50 \mathrm{J}$. The heat absorbed by the gas in the process $BC$ is $90 \mathrm{J}$.

Find the heat energy rejected or absorbed by the gas in the process $CA$.
(d) What is the net work done by the gas in the complete cycle $A B C A ?$
