Over the financial period, the company paid out 60 000 in salaries and social security contributions of 50% of that amount. The company produced 240 PCs. Closing stock of finished products was 27 units and opening stock 14 units. At the end of the financial period, the manager of the company sells the premises that he had bought for 200 000 three years ago (which was depreciated over 40 years) for 230 000, it now occupies old premises that are fully depreciated, and pays off a 12 000 loan on which the company was paying interest at 5%. What impact do these transactions have on EBITDA, operating profit and net income? Tax is levied at a rate of 35%. Over the course of the financial period, by how much did the company/the lenders/the company manager (who owns 50% of the shares) get richer/poorer?

I am not understanding how to solve this or answer it.
