11. A man purchased a cow for Rs. 3000 and sold it the same day for Rs. 3600, allowing the buyer a credit of 2 years. If the rate of interest be 10% per annum, then the man has a gain of:
- A. 0%
- B. 10%
- C. 7.5%
- D. 5%
Check answer and explanation
Answer: 0%
Explanation Formula used: Profit % = SP−CP/CP×100 Profit % = SP−CPCP×100, where SP is the selling price and CP is the cost price. Complete step-by-step solution: We are given that man (the buyer) purchases a cow for Rs. 3000 on a credit basis at a rate of interest 10% per annum for 2 years. 10% of Rs. 3000 is 10/100 ×3000=Rs.300 10100×3000=Rs.300 For 2 years, the interest is 2×300=Rs.600 2×300=Rs.600 Therefore the actual price (cost price) of the cow is 3000+600=Rs.3600 3000+600=Rs.3600 The selling price of the cow is Rs. 3600. Therefore, the profit or gain by selling the cow is ⇒Profit % = 3600−3600/ 3600 ×100 =0% ***** ND1-1-2023
