आम का क्रय मूल्य = 20 रुपये प्रति किलोग्राम
आम का विक्रय मूल्य = 30 रुपये प्रति किलोग्राम
उसके द्वारा की गई बेईमानी 1000 - 800 = 200 ग्राम
प्रयुक्त सूत्र:
लाभ % = (लाभ / क्रय मूल्य) × 100
लाभ = (विक्रय मूल्य – क्रय मूल्य)
गणना:
1000 ग्राम चीनी का क्रय मूल्य = 20 रुपये
1 ग्राम चीनी का क्रय मूल्य = 20/1000
वह केवल 800 ग्राम देता है और ग्राहक के साथ 200 ग्राम की बेईमानी करता है
इसलिए 800 ग्राम चीनी का क्रय मूल्य = (20 × 800)/1000
800 ग्राम चीनी का क्रय मूल्य = 16
चीनी का विक्रय मूल्य = 30
लाभ = 30 - 16 = 14
लाभ % = (लाभ / क्रय मूल्य) × 100
⇒ (14/16) × 100
⇒ 87.5 %
∴ दुकानदार द्वारा अर्जित लाभ 87.5% है।
Shortcut Trick
| क्रय मूल्य | विक्रय मूल्य | |
| रुपये | 20 | 30 |
| राशि | 800 | 1000 |
⇒ क्रय मूल्य : विक्रय मूल्य = 20 × 800 : 30 × 1000
⇒ क्रय मूल्य : विक्रय मूल्य = 16 : 30 ⇒ P = (30 - 16= 14)
लाभ % = (14/16) × 100 = 87.5%
