An ideal gas undergoes the cyclic process $\text{abca}$as shown in the figure. The internal energy change of the gas along the path $\text{c}\text{a}$  is $-180 \text{J}$. The gas absorb $250 \text{J}$ of heat along the path $\text{a}\text{b}$  and also absorbs $60 \text{J}$  of heat along the path $\text{bc}$. Find the work done by the gas along the path $\text{a}\text{b}\text{c}$
