164. Rahul bought 15 laptops for Rs.75000 and then he also spends Rs.3000 for transport charge. If he sells 13 laptops for Rs.83200, then what is the approximate profit percentage?

राहुल ने 15 लैपटॉप 75000 रु. में खरीदे और फिर उन्होंने परिवहन शुल्क के लिए 3000 रु. भी खर्च किए। यदि वह 13 लैपटॉप को 83200 . में बेचता है, तो अनुमानित लाभ प्रतिशत क्या है?

B. 23%
C. 27%
D. 29%
E. 31%

Option “B” is correct.

15 laptops=Rs.75000

Transport charge=Rs.3000

Total spending amount=75000 + 3000=78000

CP of one laptop=78000/15=5200

SP of one laptop=83200/13=6400

Profit-6400 – 5200=1200

Required percentage=1200/5200 * 100=23%
165. The profit earned by selling a table for Rs. 3600 is equal to the loss incurred by selling the same table for Rs. 1200. At what price should the table be sold to make 40 % profit?

एक टेबल को 3600 रुपये में बेचकर कमाया गया लाभ, 1200 रुपये में उसी टेबल को बेचकर हुए हानि के बराबर है। 40% लाभ कमाने के लिए टेबल को किस कीमत पर बेचा जाना चाहिए?

A. Rs. 3540
B. Rs. 3280
C. Rs. 3360
D. Rs. 3420
E. None of these

Option “C” is correct.

According to the question,

Profit = Loss

SP1 – CP = CP – SP2

3600 – CP = CP – 1200

3600 + 1200 = 2CP

4800 = 2CP

CP = 4800/2 = Rs. 2400

To make 40 % profit,

SP = 2400 * (140/100) = Rs. 3360
166. Mona bought a printer and sold it to Sona for Rs.2400 thereby making a profit of 20%. At what price Mona must sell the printer to earn a profit of 60%?

मोना ने एक प्रिंटर खरीदा और उसे सोना को 2400 रुपये में बेच दिया, जिससे 20% का लाभ हुआ। मोना को 60% का लाभ अर्जित करने के लिए प्रिंटर को किस कीमत पर बेचना चाहिए?

A. Rs. 2400
B. Rs. 2800
C. Rs. 3000
D. Rs. 3200
E. Rs. 3600

Option “D” is correct.

CP of printer for Mona = x

ATQ,

X* (100+20)/100 = 2400

X = 5/6 * 2400

X = 2000

So, CP of printer for Mona = 2000

To make a profit of 60%,

SP = [(100+60)/100] * 2000= Rs. 3200
167. If the marked price of a headset is 120% of its cost price and the shopkeeper allows the discount of 15%, So the shopkeeper gets the profit of Rs.800. what is the cost price of the headset?

A. Rs.30000
B. Rs.20000
C. Rs.40000
D. Rs.50000
E. Rs.60000

Option “C” is correct.

CP=100x

MP=100x * 120/100=120x

SP=120x * 85/100=102x

Profit=SP – CP

2x=800

x =400

CP=400 * 100=40000
168. The ratio of the cost price of mobile to laptop is 5:9 and the ratio of the cost price of laptop to computer is 3:2. If the computer sells at the profit of 20% and selling price of the computer is Rs.14400, then what is the difference between the cost price of mobile and laptop?

B. Rs.6000
C. Rs.7000
D. Rs.8000
E. None of these

Option “D” is correct.

Ratio of the cost price of mobile, laptop and computer = 5: 9: 6

Cost price of computer = 100/120 * 14400 = 12000

Cost price of mobile = 5/6 * 12000 = 10000

Cost price of laptop = 9/6 * 12000 = 18000

Difference = 18000 – 10000 = 8000
169. The marked price of a computer is Rs. 15000. If a shopkeeper earned a profit of 16 (2/3)% after giving a phone for purchasing of the computer and the cost price is 12000, find the percentage of discount which is equal to the price of phone.

A. 8 (2/3)%
B. 7 (2/3)%
C. 6 (2/3)%
D. 6 (1/3)%
E. 9 (2/3)%

Option “C” is correct.

CP = 12000

MP = 15000

Profit = 12000 * 50/300 = 2000

Price of phone = 15000 – (12000 + 2000) = 1000

Discount = 1000

% Discount = (1000/15000) * 100 = 6 (2/3)%
170. The cost price of the laptop is Rs.6500 and while the shopkeeper sold the laptop, he gets the profit of Rs.2000. What is the marked price of the laptop if the shopkeeper offers 15% of the discount?

MP = Rs.10000
