edited the thing ..
1) isothermal expansion
so, WAB = + 400nRlog(v2/v1)
= + 400nRlog2
2) isochoric proc. so, work done =0
3) isothermal contraction
so, WCD = 300nRlog(v1/v2)
= - 300nRlog[1/2] = - 300nRlog2
4) zero work done.
so net work done = 100nRlog2.

why the signs are opposite in calculating work

The final magnitude of work will itself tell, if it was expansion or compression
so don't make these mistakes
