ধরি, কলমের তালিকা মূল্য = y টাকা। প্রশ্নমতে, ছাড় দেওয়া হচ্ছে 20%। সুতরাং, কলমের বিক্রয় মূল্য = y - (20/100)y = 0.8y টাকা। প্রতি 10 টি কলম কেনার জন্য 2 টি কলম বিনামূল্যে দেওয়া হচ্ছে। অর্থাৎ, ক্রেতা 10 টি কলমের দাম দিচ্ছে কিন্তু 12 টি কলম পাচ্ছে। প্রতিটি কলমের ক্রয়মূল্য = x টাকা। ব্যবসায়ী প্রতিটি কলমে 20% লাভ করছেন। সুতরাং, প্রতিটি কলমের বিক্রয়মূল্য = x + (20/100)x = 1.2x টাকা। 12 টি কলমের বিক্রয়মূল্য = 12 * 1.2x = 14.4x টাকা। 10 টি কলমের বিক্রয়মূল্য = 14.4x টাকা। প্রতিটি কলমের বিক্রয়মূল্য = 14.4x / 10 = 1.44x টাকা। বিক্রয় মূল্য = তালিকা মূল্য - ছাড়। ⇒ 1.44x = 0.8y। ⇒ y = 1.44x / 0.8। ⇒ y = 1.8x। সুতরাং, কলমের তালিকা মূল্য হলো 1.8x টাকা।Related questions
