Solution: 60 Tk/kg ও 65 Tk/kg দরের দুই জাতের চা কত অনুপাতে মিশিয়ে 68.20 Tk/kg দরে বিক্রি করলে 10% লাভ হবে ? যেহেতু, মিশ্রণটি 68.2 Tk/kg বিক্রয় করলে 10% লাভ হয় । তাহলে, বিক্রয়মূল্য 110 টাকা হলে Cost = 100 টাকা বিক্রয়মূল্য 68.2 টাকা হলে Cost = Tk/kg ধরি, 60 টাকা ও 65 টাকা দরের চা যথাক্রমে x ও y কেজি করে মিশাতে হবে । প্রশ্নমতে, 60x + 65y = 62 (x + y) => 3y = 2x => x : y = 3 : 2. অর্থাৎ 3 : 2 অনুপাতে মিশাতে হবে ।Related questions
