Download Solution PDFदिलेल्याप्रमाणे
केळीचे 8 नग 5 रुपयांना विकत घेतले जातात
आणि, 5 नगांना 8 रुपयांना विकले
वापरलेले सूत्र:
नफा = वि.किं – ख.किं
नफा % = (नफा/ख.किं) × 100
गणना
8 तुकड्यांचे ख.किं = 5 रुपये ---- (1)
5 तुकड्यांचा वि.किं = 8 रुपये ---- (2)
आता, पहिल्या समीकरणाला 5 ने आणि दुसरे समीकरण 8 ने गुणा
40 तुकड्यांचे ख.किं = 25 रुपये
40 तुकड्यांचा वि.किं = 64 रुपये
नफा = विक्री किंमत – खरेदी किंमत
⇒ नफा = 64 – 25 = 39 रुपये
नफा% = (नफा/किंमत किंमत) × 100
⇒ नफा% = (39/25) × 100 = 156%
∴ नफ्याची टक्केवारी 156% आहे
Shortcut Trick
8 तुकड्यांचे ख.किं = 5 रुपये
⇒ 1 तुकड्याचा ख.किं = 5/8 रुपये
5 तुकड्यांचा वि.किं = 8 रुपये
⇒ 1 तुकड्याचा वि.किं = 8/5 रुपये
नफा = वि.किं – ख.किं
⇒ 8/5 – 5/8 = 39/40
नफा % = (नफा/ख.किं) × 100
⇒ {(39/40)/(5/8)} × 100
⇒ {(39 × 8)/(40 × 5)} × 100
⇒ 39 × 4 = 156%
∴ नफ्याची टक्केवारी 156% आहे
