181. The shopkeeper sold the article A at 20% loss and the cost price of the article A is Rs.4500. With that amount, he bought the article B and sold it at the profit of 30%. What is the overall profit or loss in the whole transaction?

दुकानदार ने वस्तु A को 20% हानि पर बेचा और वस्तु A का क्रय मूल्य 4500 रुपये है। उस राशि से, उसने वस्तु B को खरीदा और उसे 30% के लाभ पर बेच दिया। पूरे सौदे में कुल लाभ या हानि क्या है?

A. Rs.120
B. Rs.150
C. Rs.180
D. Rs.200
E. None of these

Option “C” is correct.

CP of article A=Rs. 4500

SP of article A=80/100 * 4500=Rs.3600

CP of article B=Rs. 3600

SP of article B=3600 * 130/100=Rs.4680

Total CP=4500 + 3600=Rs.8100

Total SP=3600 + 4680=Rs. 8280

Profit=8280 – 8100=Rs.180
182. A shopkeeper bought 60kg of apple at the rate of Rs.90 per kg. He sold 45% of the total quantity at the rate of Rs.100. At what price per kg (approximate value) should he sell the remaining quantity to make 25% overall profit?

एक दुकानदार ने 60 किग्रा सेब 90 रुपये प्रति किग्रा की दर से खरीदा। उसने कुल मात्रा का 45% 100 रुपये की दर से बेच दिया। 25% समग्र लाभ प्राप्त करने के लिए उसे शेष मात्रा को किस मूल्य प्रति किग्रा (अनुमानित मूल्य) पर बेचना चाहिए?

A. Rs.123
B. Rs.139
C. Rs.137
D. Rs.143
E. Rs.113

Option “A” is correct.

CP=90*60=Rs.5400

45% of 60kg=60*45/100=27kg

SP of 27kg=27*100=Rs.2700

25% of profit=5400*125/100=Rs.6750

Amount=6750-2700=4050

Remaining apple=60-27=33kg

Required amount=4050/33=Rs. 122.72
183. The shopkeeper sold two mobiles for Rs.6000 each. If one of the mobile sold at 20% profit and another one is 20% loss, then what is the profit or loss for whole transaction?

एक दुकानदार ने 6000 रुपये प्रति मोबाइल की दर से दो मोबाइल बेचे। यदि एक मोबाइल 20% लाभ पर और दूसरा 20% हानि पर बेचा जाता है, तो पूरे लेनदेन पर उसे कितना लाभ या हानि होगी?

A. No loss no profit
B. Rs.400 profit
C. Rs.600 loss
D. Rs.500 loss
E. Rs.600 profit

Option “D” is correct.

Total SP=6000 + 6000 =Rs. 12000

CP of the first mobile=100/120 * 6000=Rs. 5000

CP of second mobile=100/80 * 6000=Rs. 7500

Total CP=5000 + 7500=Rs. 12500

Loss=12500 – 12000=Rs.500
184. The shopkeeper sold the article A at 20% loss and the cost price of the article A is Rs.4500. With that amount, he bought the article B and sold it at the profit of 30%. What is the overall profit or loss in the whole transaction?

दुकानदार ने वस्तु A को 20% हानि पर बेचा और वस्तु A का लागत मूल्य 4500 रुपये है। उसी राशि से, उसने वस्तु B को खरीदा और इसे 30% के लाभ पर बेचा। पूरे लेनदेन में कुल लाभ या हानि क्या है?

A. Rs.120
B. Rs.150
C. Rs.180
D. Rs.200
E. None of these

Option “C” is correct.

CP of article A=Rs. 4500

SP of article A=80/100 * 4500=Rs.3600

CP of article B=Rs. 3600

SP of article B=3600 * 130/100=Rs.4680

Total CP=4500 + 3600=Rs.8100

Total SP=3600 + 4680=Rs. 8280

Profit=8280 – 8100=Rs.180
185. Ratio of the cost price of mobile and the selling price of laptop is 1:1 and the shopkeeper sold the mobile at 10% loss and laptop at 20% profit. If the selling price of mobile and laptop together is Rs.19000, what is the approximate total profit or loss?

मोबाइल की लागत मूल्य और लैपटॉप की बिक्री मूल्य का अनुपात 1: 1 है और दुकानदार ने मोबाइल को 10% की हानि पर और लैपटॉप को 20% लाभ पर बेचा। यदि एक साथ मोबाइल और लैपटॉप का बिक्री मूल्य रु. 19000 है, तो अनुमानित कुल लाभ या हानि क्या है?

A. No gain no loss
B. Rs.555 loss
C. Rs.667 profit
D. Rs.480 loss
E. Rs.499 profit

Option “C” is correct.

CP of mobile = m

CP of laptop = l

SP of mobile = x

SP of laptop = y

x+ y = 19000

m = y

x = 90/100 * m

x = 90/100 * y

90/100 * y + y = 19000

190y/100 = 19000

y = 10000

x = 9000

m = 9000 * 100/90 = 10000

y = 120/100 * l

10000 = 120/100 * l

l = 1000000 / 120 = 50000/6

Total CP = 10000 + 50000/6 = Rs.18333.33

Profit = 19000 – 18333.33 = 666.667
186. A shopkeeper has certain number of laptops. He sold 40% of the laptops at the profit of 20% and the rest is sold at 10% loss. If he earned the overall profit is Rs.10, find the number of laptops?

एक दुकानदार के पास निश्चित संख्या में लैपटॉप होते हैं। उसने 20% के लाभ पर 40% लैपटॉप बेचे और बाकी 10% हानि पर बेचा। यदि उसका कुल लाभ 10 रूपये है, तो लैपटॉप की संख्या ज्ञात कीजिए?

A. 200
B. 300
C. 400
D. 500
E. 800

Option “D” is correct.

Number of laptops = x

SP of 40% of the laptops = 40x/100 * 120/100 = 12x/25

SP of 60% of the laptops = 60x/100 * 90/100= 27x/50

Total selling price = 12x/25 + 27x/50

= 51x/50 = 1.02x

Profit = 1.02x – x = 0.02x

0.02x = 10

x = 500
187. A shopkeeper bought two articles at same price. He sold one of the articles at the profit of 40 %. If on selling the second article, he incurred a loss, which was one-fourth of profit earned on selling the first article, then find the overall profit %?

एक दुकानदार ने एक ही कीमत पर दो वस्तुएं खरीदी। उन्होंने 40% के लाभ पर एक वस्तु बेची। यदि दूसरी वस्तु को बेचने पर, उसे जो नुकसान हुआ, वो पहली वस्तु को बेचने पर अर्जित लाभ का एक-चौथाई था, तो समग्र लाभ% ज्ञात कीजिये?

A. 10 %
B. 25 %
C. 15 %
D. 20 %
E. None of these

Option “C” is correct.

Let the cost price be Rs. 100,

CP1 = 100, CP2 = 100, Total cost price = 200

Total selling price = 100 * (140/100) + [100 – 40 * (1/4)] = 230

Profit % = (30/200) * 100 = 15 %
188. The selling price a product of company A and B is Rs.25 and Rs.20 respectively and profit of them is 25% and 30% respectively. If the number of products sold by company A and B is 150 and 130 respectively, then find the total manufacturing cost of company A and company B.

कंपनी A और B के उत्पाद का विक्रय मूल्य क्रमशः रु.25 और रु.20 है और इनका लाभ क्रमशः 25% और 30% है। यदि कंपनी A और B द्वारा बेचे जाने वाले उत्पादों की संख्या क्रमशः 150 और 130 है, तो कंपनी A और कंपनी B की कुल विनिर्माण लागत ज्ञात कीजिये।

A. Rs.5000
B. Rs.6250
C. Rs.7850
D. Rs.4850
E. None of these

Option “A” is correct.

For Company A, Manufacturing cost = 25 * 100/125 * 150 = Rs.3000

For Company B, manufacturing cost = 20 * 100/130 * 130 = Rs.2000

Total cost = 3000 + 2000 = Rs.5000
189. A man buys a door and TV set for Rs. 40000. If he sells the doors at 20% profit and the TV set at Rs. 30 % profit, then he earns a total profit of Rs. 10500. Find the selling price of a TV set?

एक व्यक्ति 40000 रुपये में एक दरवाजा और टीवी सेट खरीदता है। यदि वह 20% लाभ पर दरवाजे और 30% लाभ पर टीवी सेट का विक्रय करता है, तो वह 10500 रुपये का कुल लाभ को अर्जित करता है। टीवी सेट का विक्रय मूल्य ज्ञात कीजिए?

A. Rs. 30000
B. Rs. 31500
C. Rs. 32500
D. Rs. 34000
E. None of these

Option “C” is correct.

Let the cost price of door and TV set be x and y respectively,

x + y = 40000 —> (1)

(20/100)*x + (30/100)*y = 10500

2x + 3y = 105000 —> (2)

By solving the equation (1) and (2), we get,

x = 15000, y = 25000

The selling price of TV set = 25000*(130/100) = Rs. 32500

(Or)

Percentage of total profit = (10500/40000)*100 = 26.25%

= > 375: 625

= > 3: 5

8’s = 40000

1’s = 5000

Cost price of TV set = 5’s = Rs. 25000

Selling price of TV set = 25000*(130/100) = Rs. 32500
190. Meeta bought an item for Rs.450. She marked the price of the item is 20% above the cost price and sold it at a discount of 5% on the marked price. She bought another item for Rs.600, She marked the price of the item is 25% above the cost price and sold it at a discount of 10% on marked price. Find her approximate overall profit percentage after selling both the items.

मीता ने 450 रुपये में एक वस्तु खरीदा। उसने लागत मूल्य से 20% ऊपर वस्तु को अंकित किया और उसे अंकित मूल्य पर 5% की छूट पर बेचा। उसने 600 रुपये में एक ओर वस्तु खरीदी। उसने लागत मूल्य से 25% ऊपर वस्तु को अंकित किया और उसे अंकित मूल्य पर 10% की छूट पर बेचा। दोनों वस्तुओं को बेचने के बाद उसका अनुमानित समग्र लाभ प्रतिशत ज्ञात करें।

A. 11%
B. 15%
C. 13%
D. 17%
E. 19%

Option “C” is correct.

Total cost price = 450 + 600 = Rs.1050

Selling price of the first item = 450 x 120/100 x 95/100 = Rs.513

Selling price of the second item = 600 x 125/100 x 90/100 = Rs.675

Total selling price = 513 + 675 = Rs.1188

Profit percentage = (1188 – 1050)/1050 x 100

= 138/1050 x 100

= 13.14%

= 13% approx.
