After that he spent 10% of the cost price in interior decoration and lawn of the house. At what price should he sell the house to earn a profit of 25%?  Choose the correct choice: A) Rs. 9 lakh B) Rs. 7.99 lakh C) Rs. 7.92 lakh D) Rs. 7 lakh E) None of These
Solution: Let the marked price be 100.   100 == 20% ↓(discount)==&gt; 80 == 10% ↓(discount)==&gt; 72(CP) == 10% ↑(interior)==&gt; 79.2(Total CP)   Now, selling price would be 25% above the Total cost price.   SP = 79.2 + 25% of 79.2   SP = 99   Now, On comparing,   100 ==&gt; 800000   99 ==&gt; (800000/100) *99 ==&gt; 7, 92,000   So,   SP = Rs. 7, 92, 000.   Answer: Option Rs. 7.92 lakh
