Which of the following is not correct equation?

[amp_mcq option1=”Purchases + opening stock – cost of goods sold = closing stock” option2=”Opening stock + purchases – closing stock = cost of goods sold” option3=”Closing stock – cost of goods sold – purchases = Opening stock” option4=”Cost of goods sold + closing stock – purchases = Opening stock” correct=”option3″]

The correct answer is C. Closing stock – cost of goods sold – purchases = Opening stock.

The equation for cost of goods sold is:

Cost of goods sold = Opening stock + Purchases – Closing stock

Therefore, the equation for opening stock is:

Opening stock = Cost of goods sold + Purchases – Closing stock

The equation for closing stock is:

Closing stock = Cost of goods sold + Purchases – Opening stock

Therefore, the equation C. Closing stock – cost of goods sold – purchases = Opening stock is not correct.
