दिया गया है:

कुल माल का क्रय मूल्य = ₹450

10% हानि पर बेचा गया अंश = 1/3

आवश्यक कुल लाभ = 20%

प्रयुक्त सूत्र:

कुल विक्रय मूल्य = क्रय मूल्य x (1 + लाभ%)

पहले भाग का विक्रय मूल्य = पहले भाग का क्रय मूल्य x (1 - हानि%)

दूसरे भाग का विक्रय मूल्य = दूसरे भाग का क्रय मूल्य x (1 + x%)

गणना:

पहले भाग का क्रय मूल्य = 1/3 x 450 = 150

दूसरे भाग का क्रय मूल्य = 2/3 x 450 = 300

पहले भाग का विक्रय मूल्य = 150 x (1 - 10/100) = 150 x 0.9 = 135

कुल विक्रय मूल्य = 450 x (1 + 20/100) = 450 x 1.2 = 540

मान लीजिये दूसरे भाग पर आवश्यक लाभ % x% है

दूसरे भाग का विक्रय मूल्य = 300 x (1 + x/100)

कुल विक्रय मूल्य = पहले भाग का विक्रय मूल्य + दूसरे भाग का विक्रय मूल्य

⇒ 540 = 135 + 300 x (1 + x/100)

⇒ 540 - 135 = 300 x (1 + x/100)

⇒ 405 = 300 x (1 + x/100)

⇒ 405 ÷ 300 = 1 + x/100

⇒ x/100 = 0.35

⇒ x = 35%

∴ शेष भाग को 35% के लाभ पर बेचा जाना चाहिए।
