C. 28%
D. 26%
E. None of these

D = 28%
142. A shopkeeper marks the price of the article is 20% above its cost price and also offers 10% of the discount. Find the profit percentage?

Profit = 1.08x – x = 0.08x

Profit percentage = 0.08x/x * 100 = 8%

850 + 710 = 2x

1560 = 2x

x = 780

149. A shopkeeper bought two articles A and B such that he had a Profit of 15% and 20% on selling article A and B respectively. Selling price of articles A and B is Rs.230 and Rs.420 respectively. At what price must that items be sold together in order to gain 30%?

एक दुकानदार ने दो वस्तुएँ A और B इस प्रकार खरीदी कि वस्तु A और B को बेचने पर उसे क्रमशः 15% और 20% का लाभ हुआ। वस्तु A और B का विक्रय मूल्य क्रमशः 230 रुपये और 420 रुपये है। 30% का लाभ प्राप्त करने के लिए वस्तुओं को किस कीमत पर एक साथ बेचा जाना चाहिए?

B. Rs.695
C. Rs.700
D. Rs.740
E. None of these

Option “E” is correct.

SP of A = 230

Profit% on A = 15%

CP of A = 230 * 100/115 = 200

SP of B = 420

Profit% on B = 20%

CP of B = 420 * 100/120 = 350

Total CP = 200 + 350 = 550

Now, to earn a total profit of 30% on both item together, selling price = 130% of 550 = Rs.715
150. Praveen is a computer shop owner. He purchases the components of a desktop for Rs 6200 and then he spends further Rs 2400 on labour charge to assemble the desktop. If he sells 18 desktops for Rs 175000, then what is the approximate profit percentage?

प्रवीण कंप्यूटर दुकान का मालिक हैं। वह डेस्कटॉप के घटकों को 6200 रुपये में खरीदता है और फिर सिस्टम को बनाने के लिए श्रम शुल्क पर 2400 रुपये खर्च करता है। यदि वह 175000 रुपये में 18 डेस्कटॉप बेचता है तो इस मामले में अनुमानित लाभ प्रतिशत क्या है?

A. 13%
B. 11.5%
C. 12.2%
D. 14.35%
E. 8.9%

Option “A” is correct.

Total cost of one desktop = Rs (6200 + 2400) = Rs 8600

Selling price of one desktop = Rs (175000/18) = Rs 9722.2

Profit% = [(9722.2-8600)/8600] * 100 = 13% (Approx)
