মনেকরি, মোট বিক্রয় = x টাকা ∴ কমিশন = 10000 এর 5% + (x - 10000) এর 4% = 10000 × 5/100 + (x - 10000) × 4/100 = (50000/100) + (4x - 40000)/100 = (50000 + 4x - 40000)/100 = (10000 + 4x)/100 = 100 + 4x/100 = 100 + x/25 প্রশ্নমতে, x - (100 + x/25) = 31100 ⇒ x - 100 - x/25 = 31100 ⇒ x - x/25 = 31100 + 100 ⇒ (25x - x)/25 = 31200 ⇒ 24x/25 = 31200 ⇒ x = (31200 × 25)/24 ⇒ x = 32500 টাকাRelated questions
