Solution: অনুবাদঃ একটি দোকান থেকে Asif একটি রেডিও ক্রয় করলো এবং এটি Rahim এর নিকট বিক্রয় করে সে 20% লাভ করলো । কিছু মাস পরেই Rahim ঐ রেডিওটি 15% ক্ষতিতে Fahad এর নিকট বিক্রয় করলো । Fahad এর ক্রয়মূল্য 510 টাকা হলো রেডিওটির প্রকৃতমূল্য কত ছিল ? মনে করি, Radio'র প্রকৃত মূল্য বা Original Price = x টাকা প্রশ্নমতে, x 1.2 0.85 = 510 => x 1.2 0.85 = 510 => x = Shortcut: A + B + - সূত্রে A = 20 এবং B = - 15 বসালে পাই Net effect = 20 + (- 15) + = 20 - 15 - 3 = 2% 2% বৃদ্ধিতে Radio'র নতুন মূল্য (100 + 2) = 102 টাকা হলে Original Price 100 টাকা Radio'র নতুন মূল্য 510 টাকা হলে Original price = = 500 টাকাRelated questions
