প্রশ্নে বলা হচ্ছে, A, B এর নিকট একটি ঘড়ি 20% লাভে বিক্রয় করলো এবং B, C এর নিকট এটি 10% ক্ষতিতে বিক্রয় করলো । C যদি ঘড়িটি 216 টাকা দিয়ে কিনে থাকে তবে A ঘড়িটি কত টাকায় বিক্রয় করেছিল ? ধরি, A এর ক্রয়মূল্য x টাকা B এর ক্রয়মূল্য = ( x+x এর 20% ) = 1.20 x টাকা C এর ক্রয়মূল্য = ( 1.20x - 10% of 1.20x ) = { 1.20x - (10×1.20x/100) } = ( 1.20x - 0.120x ) = 1.08 x টাকা প্রশ্নমতে, 1.08 x = 216 => x = 216/1.08 = 216×100/108 = 200 ∴ x = 200 A এর ক্রয়মূল্য 200 টাকাRelated questions
