Answer:
ROE would have changed by 8.52%
Explanation:
First we calculate the current ROE using Dupont Equation which gives ROE as,
ROE = Net Income/Sales * Sales/Total Assets * Total Assets/Equity
or
ROE = Net Profit Margin * Total Assets Turnover * Equity Multiplier
The condition says that the net income could have increased to 20850 but other factors will remain constant. Thus, to calculate new ROE, we will calculate the new Net Profit margin but the total assets turnover and the equity multiplier will remain constant as sales assets and capital structure is not changing.
