প্রশ্নে বলা হচ্ছে, এক দোকানদার একটি TV বিক্রয় করে 45% মুনাফা করে। ছাড়ে বিক্রয়ের সময়, তার মুনাফা কমিয়ে 40% করলো। এর ফলে তার বিক্রয় 10% বেড়ে গেল। নতুন মুনাফা ও আগের মুনাফার অনুপাত কত? মনেকরি, 45% profit-এ TV sell করে = x টি। ∴ x টি TV- তে Profit = x × 45% = 0.45x আবার, 10% sales বৃদ্ধিতে New sales (x + x x 10% ) = 1.10x ∴ Profit (1.10x x 40%) = 110x/100 x 40/100 = 0.44x ∴ New profit: Usual profit = 0.44x : 0.45x = 0.44x/0.45x = 44/45 = 44 : 45Related questions
