एक दुकानदार 450 किलो तांदूळ ₹ 40 प्रति किलो दराने विकण्याचा दावा करतो परंतु एक किलो वजनाऐवजी 900 ग्रॅम वजन वापरतो. उर्वरित तांदूळ काळ्या बाजारात विकून तो ₹2,520 चा नफा कमावतो. तांदळाच्या मूळ किमतीचे काळ्या बाजारातील किमतीचे गुणोत्तर किती आहे?

दिलेल्याप्रमाणे:

किंमत प्रति किलो = ₹40

वापरलेले वजन = 900 ग्रॅम (1 किलो ऐवजी)

एकूण तांदूळ विकल्याचा दावा केला = 450 किलो

काळ्या बाजारात झालेला नफा = ₹2,520

वापरलेले सूत्र:

प्रत्यक्षात विकलेले वजन = (वापरलेले वजन/1000) × एकूण तांदूळ विकल्याचा दावा केला

उरलेला तांदूळ = एकूण तांदूळ - प्रत्यक्षात विकलेले वजन

काळ्या बाजार भाव प्रति किलो = (नफा / शिल्लक तांदूळ)

गणना:

प्रत्यक्षात विकलेले वजन = (900/1000) × 450 = 0.9 × 450 = 405 किलो

उरलेला तांदूळ = 450 - 405 = 45 किलो

काळ्या बाजार भाव प्रति किलो = नफा / उरलेला तांदूळ = 2520 / 45

⇒ काळ्या बाजारातील किंमत प्रति किलो = ₹56

आता, काळ्या बाजारातील किमतीचे मूळ किमतीचे गुणोत्तर:

⇒ गुणोत्तर = 56 / 40 = 7 / 5

∴ काळ्या बाजारातील किमतीचे मूळ किमतीचे योग्य गुणोत्तर 7:5 आहे.
