The correct answer is A. Rs. 10,000.
The formula for net profit margin is:
Net profit margin = Net profit / Total revenue
The formula for total assets turnover is:
Total assets turnover = Net sales / Average total assets
We are given that the total assets turnover is 3 times the net profit margin, and the net profit margin is 10%. We are also given that the total assets are Rs. 1,00,000.
We can use the formula for total assets turnover to calculate the net sales:
Total assets turnover = Net sales / Average total assets
3 = Net sales / (1,00,000 / 2)
6 = Net sales
We can then use the formula for net profit margin to calculate the net profit:
Net profit margin = Net profit / Total revenue
10% = Net profit / 6
Net profit = 6000
Therefore, the net profit is Rs. 10,000.
Option B is incorrect because the net profit is not Rs. 15,000.
Option C is incorrect because the net profit is not Rs. 25,000.
Option D is incorrect because the net profit is not Rs. 30,000.
