Q31.	A fruit seller bought 200 kgs of apples at the rats of Rs.5 per kg. He found that 50 kgs of them were inferior quality and sold them at the rate of Rs. 4 per kg. He sold the remaining apples at Rs. 6 per kg. Find the over all profits or loss % in this transaction?

1)	5%	2)	8%
3)	10%	4)	12%
5)	None of these

Answer : 10%
Explanation : C.P of the all apples = 200 x 5 = Rs.1000/

S.P of 50 kg = 50 x 4 = Rs.200/

S.P of 150 apples = 150 x 6 = Rs.900/

So, total selling price = 200 + 900 =Rs.1100

Profit = 1100-1000 = 100

So, % of profit = (100/1000) x 100 = 10%

Q32.	Alok bought a table and paid 10 % less than the original price. He sold it with 30% profit on the price he had paid. What percentage of profit did he earn on the original price ?

1)	12%	2)	15%
3)	16%	4)	17%
5)	None of these

Answer : 17%
Explanation :

Let, the original price =100

Then the price at which he purchased (CP) = 90% of 100 = 90

Profi t = 30%

So, S.P = (90 /100) x 130 = 117

Thus, profit % = (117 - 100)/100 = 17%

Q34.	A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. What is his profit percentage ?

1)	4%	2)	5%
3)	6%	4)	8%
5)	None of these

Answer : 5%
Explanation : CP of 1st variety rice = 20

CP of 2nd variety rice =36

CP of the 56 kg rice mixture = (26�20+30�36) = 520 + 1080 = 1600

SP of the 1 kg rice mixture = 30

SP of the 56 kg rice mixture = 30�56 = 1680

Gain = SP − CP = 1680 − 1600 = 80

Gain % = (Gain x CP) � 100 = (80/1600 )�100 = (100/20) = 5%

Q35.	When an item is sold for Rs. 6000, the owner loses 20%. At what price should that item be sold to get a gain of 20% ?

1)	Rs. 7500	2)	Rs. 8000
3)	Rs. 9000	4)	Rs. 12000
5)	None of these

Answer : Rs. 9000
Explanation : The C.P of the item = (6000/80) x100 = Rs. 7500

After 20% profit, the S.P of the item = 7500 x (120/100) = Rs.9000/

Q36.	The percentage profit earned by selling an item for Rs. 1920 is equal to the percentage loss incurred by selling the same item for Rs. 1280. At what price should the item be sold to make 25% profit ?

1)	Rs.1600	2)	Rs.2000
3)	Rs.2400	4)	Rs.3000
5)	None of these

Answer : Rs.2000
Explanation : Short-Cut Method:

C.P = (S.P1 + S.P2)/2 = 1920 + 1280 = 3200/2 = 1600

So, S.P = 1600 x 125/100 = Rs.2000/

Q37.	In a certain store, the profit is 250% of the cost. If the cost increases by 20% but the selling price remains constant, approximately what percentage of the selling price is the profit ?

1)	55%	2)	60%
3)	66.66%	4)	75%
5)	None of these

Answer : 66.66%
Explanation :

Let C.P.= Rs. 100. Then, Profit = Rs. 260, S.P. = Rs. 360.

New C.P. = 120 % of Rs. 100 = Rs. 120

New S.P. = Rs. 360.

Profit = Rs. (360 - 120) = Rs.240.

Required percentage = (240/360) x 100 = 66.66%

Q38.	On selling 20 pens at Rs. 720, there is a loss equal to the cost price of 8 pens. The cost price of a pens is:

1)	Rs. 45	2)	Rs. 50
3)	Rs. 55	4)	Rs. 60
5)	None of these

Answer : Rs. 60
Explanation :

(C.P. of 20 pens) - (S.P. of 20 pens) = (C.P. of 8 pens)

C.P. of 12pens = S.P. of 17pens = Rs.720.

C.P. of 1 pens = (720/12) = 60

Q39.	A person buys an old TV for Rs. 4500 and spends Rs. 300 on its repairs. If he sells the scooter for Rs. 6000, his gain percent is:

1)	16%	2)	18%
3)	20%	4)	25%
5)	None of these

Answer : 25%
Explanation :

Cost Price (C.P.) = Rs. (4500 + 300) = Rs. 4800.

Selling Price (S.P.) = Rs. 6000.

Gain = (S.P.) - (C.P.) = Rs.(6000 - 4800) = Rs. 1200.

Gain % = = 25%

1)	Rs.575	2)	Rs.750
3)	Rs.552	4)	Rs.552
5)	None of these

Answer : Rs.552
Explanation :

Given profit is 25%, S.P. = Rs.600

So, C.P. = (600/125)/100 = Rs. 480

So, Initial S.P. = (480/100) x 100 =Rs. 552.

SHORT-CUT METHOD:

(600/125) x (115/100) x 100 = 552
