दिलेले आहे​:

आंब्याची खरेदी किंमत = 20 रुपये प्रति किलो

आंब्याची विक्री किंमत = 30 रुपये प्रति किलो

1000 - 800 = 200 ग्रॅमने फसवणूक

वापरलेले सूत्र:

नफा % = (नफा / खरेदी किंमत) × 100

नफा = (विक्री किंमत – खरेदी किंमत)

गणना:

1000 ग्रॅम साखरेची खरेदी किंमत = 20 रुपये

1 ग्रॅम साखरेची खरेदी किंमत = 20/1000

त्याने फक्त 800 ग्रॅम दिले आणि 200 ग्रॅम घेऊन ग्राहकाची फसवणूक केली

तर 800 ग्रॅम साखरेची खरेदी किंमत = (20 × 800)/1000

800 ग्रॅम साखरेची खरेदी किंमत = 16

साखरेची विक्री किंमत = 30

नफा = 30 - 16 = 14

नफा % = (नफा / खरेदी किंमत) × 100

⇒ (14/16) × 100

87.5 %

∴दुकानदारांनी मिळवलेला नफा 87.5% आहे

Shortcut Trick

  ख. किं वि.किं
रुपये 20 30
रक्कम 800 1000


⇒ ख. किं : वि.किं = 20 × 800 : 30 × 1000

⇒ ख. किं : वि.किं = 16 : 30 ⇒ P = (30 - 16= 14)

नफा % = (14/16) × 100 = 87.5%
