सूरज 7 रुपये में 5 की दर से टॉफ़ी खरीदता है
और वह 4 रुपये में 3 की दर से टॉफ़ी बेचता है
सूत्र:
लाभ = S.P - C.P
हानि = C.P - S.P
लाभ% = (लाभ × 100)/C.P
हानि% = (हानि × 100)/C.P
जहाँ, S.P = विक्रय मूल्य, C.P = क्रय मूल्य
गणना:
माना टॉफ़ी की संख्या 15 है, (5, 3) का लघुत्तम समापवर्तक
⇒ 15 टॉफ़ी का क्रय मूल्य = 15 × (7/5) = 21 रुपये
⇒ 15 टॉफ़ी का विक्रय मूल्य = 15 × (4/3) = 20 रुपये
⇒ हानि = C.P - S.P = 21 - 20
⇒ हानि = 1 रुपया
हानि% = (हानि × 100)/C.P
⇒ हानि% = (1 × 100)/21
⇒ हानि% = 100/21
∴ सूरज को (100/21)% की हानि होती है।
