The most common version of this type of question. Note that the amount of depreciation may be a number other than $10. To answer this question, take the three statements one at a time.
First, the income statement: depreciation is an expense so operating income (EBIT) declines by $10. Assuming a tax rate of 40%, net income declines by $6. Second, the cash flow statement: net income decreased $6 and depreciation increased $10 so cash flow from operations increased $4. Finally, the balance sheet: cumulative depreciation increases $10 so Net PP&E decreases $10. We know from the cash flow statement that cash increased $4. The $6 reduction of net income caused retained earnings to decrease by $6. Note that the balance sheet is now balanced. Assets decreased $6 (PP&E -10 and Cash +4) and shareholder’s equity decreased $6.
You may get the follow-up question: If depreciation is non-cash, explain how this transaction caused cash to increase $4. The answer is that because of the depreciation expense, the company had to pay the government $4 less in taxes so it increased its cash position by $4 from what it would have been without the depreciation expense.
