The correct answer is B. 29.17%.
The rate of return on investment (ROI) is a measure of profitability. It is calculated by dividing the net profit by the total investment. In this case, the net profit is P3,500,000 and the total investment is P12,000,000 (P10,000,000 + P2,000,000). Therefore, the ROI is 29.17%.
Option A is incorrect because it is the rate of return on the fixed capital investment only. Option C is incorrect because it is the rate of return on the working capital only. Option D is
incorrect because it is the rate of return on the total investment, but it is rounded to the nearest whole number.The formula for calculating ROI is:
ROI = (Net Profit / Total Investment) * 100%
In this case, the ROI is:
ROI = (P3,500,000 / P12,000,000) * 100% = 29.17%
