दिलेले आहे:

30 रुपये प्रति किलो किंमतीची साखर आणि 65 रुपये प्रति किलो किंमतीची साखर मिसळली पाहिजे, 

नफा = 10%, विक्री किंमत = 66 रुपये 

सूत्र:

विक्री किंमत = नफा)/खरेदी किंमत × 100

गणना:

संपूर्ण मिश्रणाची किंमत x रुपये समजू 

⇒ x = 66 × 100/110

⇒ x = 60 रुपये 

⇒ आवश्यक गुणोत्तर = (65 – 60)/(60 – 30)

⇒ गुणोत्तर = 5 : 30 = 1 : 6

आवश्यक गुणोत्तर 1 : 6 आहे.

प्रमिश्रण पद्धतीने

30             65

        60

5                30

1       :        6

आवश्यक गुणोत्तर = 1 : 6
