A process may go wrong in two ways, call them A or B$.$ Both these ways are equally likely. If the cause is A then it causes a loss of Rs$\mathrm{.}100,000$ to the company if it is not repaired. If it is repaired, there is $60\%$ chance of restricting the loss to Rs$\mathrm{.}40,000$ and a $40\%$ chance of restricting the loss to Rs$\mathrm{.}70,000.$ If the cause is B then the repairing operation has no effect and the loss to the company would be Rs$\mathrm{.}80,000.$ Repairing costs Rs$\mathrm{.}25,000.$

a$.$If the cause of the process going wrong is A$,$ and the process is repaired, then what would the net loss to the company?
