At a selling price of Tk. 275 a book yield 25% profit. What selling price will yield the profit of 10%? Correct Answer 242
Let the actual price be A. Then, A + 25% of A = 275 or, A + 0.25A = 275 or, 1.25A = 275 or, A = 275/1.25 = 220 TK. So, selling price at 10% profit = 220 + 10% of 220 = 220 + 22 = 242 TK
