On selling 17 balls at Rs. 720, there is a loss equal to the cost price of 5 balls. The cost price of a ball is:
A) Rs. 45 | B) Rs. 50 |
C) Rs. 55 | D) Rs. 60 |
D) Rs. 60
Explanation:
(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)
=> C.P. of 12 balls = S.P. of 17 balls = Rs.720.
=>C.P. of 1 ball = Rs. 720 / 12 = Rs. 60
When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?
A) Rs. 21,000 | B) Rs. 22,500 |
C) Rs. 25,300 | D) Rs. 25,800 |
C) Rs. 25,300
Explanation:
85 : 18700 = 115 : x
=> X = (18700 x 115 / 85 = 25,300.
Hence, S.P. = Rs. 25,300
100 oranges are bought at the rate of Rs. 350 and sold at the rate of Rs. 48 per dozen. The percentage of profit or loss is:
A) 14 2/7 % gain | B) 15% gain |
C) 14 2/7 % loss | D) 15% loss |
A) 14 2/7 % gain
Explanation:
C.P. of 1 orange = Rs (350/100) = Rs. 3.50
S.P. of 1 orange = Rs. (48/12) = Rs. 4
Gain% = (0.50/3.50 Γ100) % = 100/7% = 14 2/7%
A shopkeeper sells one transistor for Rs. 840 at a gain of 20% and another for Rs. 960 at a loss of 4%. His total gain or loss percent is:
A) 5 15/17% loss | B) 5 15/17% gain |
C) 6 2/3% gain | D) None of these |
B) 5 15/17% gain
Explanation:
C.P. of 1st transistor = Rs (100/120X 840) = Rs. 700
C.P. of 2nd transistor = Rs. (100/96X 960) = Rs. 1000
So, total C.P. = Rs. (700 + 1000) = Rs. 1700.
Total S.P. = Rs. (840 + 960) = Rs. 1800.
Gain % = (100/1700X 100)% = 5 15/17%
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. His profit percent is:
A) No profit, no loss | B) 5% |
C) 8% | D) 10% |
B) 5%
Explanation:
C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
Gain = (80/1600 x 100)% = 5%.
each one of them at the rate of Rs. 33. What was his percentage profit?
A) 3.5 | B) 4.5 |
C) 5.6 | D) 6.5 |
C) 5.6
Explanation:
Cost Price of 1 toy = Rs.375/12 = Rs. 31.25
Selling Price of 1 toy = Rs. 33
So, Gain = Rs. (33 - 31.25) = Rs. 1.75
Profit % = (1.75/31.25 x 100)%= 28/5% = 5.6%
A man buys a cycle for Rs. 1400 and sells it at a loss of 15%. What is the selling price of the cycle?
A) Rs. 1090 | B) Rs. 1160 |
C) Rs. 1190 | D) Rs. 1202 |
C) Rs. 1190
Explanation:
S.P. = 85% of Rs. 1400 = Rs ( 85/100 x 1400) = Rs.1190.
A, B and C enter into a partnership. A invests some money at the beginning, B invests double the amount after 6 months, and C invests thrice the amount after 8 months. If the annual gain be Rs. 18,000. A's share is?
A) Rs. 5,750 | B) Rs. 6,000 |
C) Rs. 7,200 | D) Rs. 7,500 |
B) Rs. 6,000
Explanation:
x*12 : 2x*6: 3x*4
1:1:1
1/3 * 18000 = 6000
By selling an article at Rs. 800, a shopkeeper makes a profit of 25%. At what price should he sell the article so as to make a loss of 25%?
A) Rs. 460 | B) Rs. 480 |
C) Rs. 500 | D) Rs. 520 |
B) Rs. 480
Explanation:
SP = 800, Profit = 25%
CP = (SP)*[100/(100+P)]
= 800 * [100/125] = 640
Loss = 25% = 25% of 640 = Rs. 160
SP = CP - Loss = 640 - 160 = Rs. 480
Amit bought 160 shirts at the rate of Rs. 225/shirt. The transport expenditure was Rs. 1,400. He paid an octroi at the rate of Rs. 1.75/shirt and labour charges were Rs. 320. What should be the selling price of 1 shirt, if he wants a profit of 20%?
A) Rs. 260 | B) Rs. 275 |
C) Rs. 280 | D) Rs. 285 |
D) Rs. 285
Explanation:
Total CP per shirt = 225 + 1400/160 + 1.75 + 320/160 = Rs. 237.5
SP = CP[(100 + profit%)/100]
= 237.5 * [(100 + 20)/100] = Rs. 285
Profit after selling a commodity for Rs. 425 is same as loss after selling it for Rs.355. The cost of the commodity is:
A) Rs. 385 | B) Rs. 390 |
C) Rs. 395 | D) Rs. 400 |
B) Rs. 390
Explanation:
Let C.P = Rs. X
425 β X = X β 355 (or)
2X = 780 or X = 390
If two mixers and one T.V cost Rs. 7000. While two T.V s and one mixer cost Rs. 9800. The value of one T.V is
A) Rs. 3,200 | B) Rs. 3,600 |
C) Rs. 4,200 | D) Rs. 4,600 |
C) Rs. 4,200
Explanation:
2X + Y = 7000
X + 2Y = 9800
Solving (i) and (ii), we get Y = 4200
Bhajan Singh purchased 120 reams of paper at Rs. 80 per ream. He spent Rs. 280 on transportation. Paid octrai at the rate of 40 paise per ream and paid Rs. 72 to the coolie. If he wants to have a gain of 8 %. What must be the selling price per ream ?
A) Rs. 86 | B) Rs. 88 |
C) Rs. 90 | D) Rs. 92 |
C) Rs. 90
Explanation:
C.P of 120 reams = Rs. (120 Γ 80 + 280 + 72 + 120 Γ 40) = Rs. 10000
C.P of 1 ream = (10000/120) = Rs. (250/3)
S.P of 1 ream = Rs. (108/100 Γ 250/3) = Rs. 90
If an article is sold at a loss of 66 2/3%, what is the loss in terms of the selling price ?
A) 50% | B) 100% |
C) 150% | D) 200% |
D) 200%
Explanation:
Let the C. P. = 100
β΄ Amount of loss = 66 2/3 or 200/3
β S. P = 100 β 66 2/3 = 33 1/3 or 100/3
β΄ Loss expressed in terms of S. P. = 100 Γ (200/3)/(100/3) 100 = 200%
A shopkeeper bought 150 pen drives at the rate of Rs. 500 per pen drive. He spent Rs. 500 on transportation and packing. If the marked price of pen drive is Rs. 520 per pen drive and the shopkeeper gives a discount of 5% on the marked price then what will be the percentage profit gained by the shopkeeper ?
A)1.2% | B) 3.8% |
C) 4.5% | D) 5.5% |
B) 3.8%
Explanation:
C.P. of 150 calculators = 150 * 500 = Rs. 75000
β΄ Total C.P. = 75000 + 500 = Rs. 75500
Marked price of 150 calculator = 150 * 570 = Rs. 82500
Selling price after discount = 82500 * 95 / 100 = Rs. 78375
β΄ percentage profit = [(78375 β 75500) / 75500] * 100 = 3.8%
An article is sold at 25% profit. If the CP and the SP of the article are increased by Rs 60 and Rs 30 respectively, the profit% decreases by 15%. Find the cost price of the article.
A) Rs. 190 | B) Rs. 240 |
C) Rs. 285 | D) Rs. 305 |
B) Rs. 240
Explanation:
CP = x, then SP = (125/100)*x = 5x/4
New CP = (x+60), new SP = (5x/4 + 30), new profit% = 25-15 = 10
So (5x/4 + 30) = (110/100) * (x+60)
Solve, x = 240
A person sold a pen at Rs. 96 in such a way that his percentage profit is same as the cost price of the watch. If he sells it at twice the percentage profit of its previous percentage profit then new selling price will be ?
A) Rs. 132 | B) Rs. 150 |
C) Rs. 180 | D) Rs. 192 |
A) Rs. 132
Explanation:CP = x
Profit Percentage = x%
SP = x(100 + x)/100
x(100 + x)/100 = 96
x = 60
Profit Percentage = 60%
New SP = 60 * 220 / 100 = 132
A and B, there are two companies, selling the packs of cold-drinks. For the same selling price A gives two successive discounts of 10% and 25%. While B sells it by giving two successive discounts of 15% and 20%. What is the ratio of their marked price ?
A) 143 : 144 | B) 19 : 11 |
C) 136 : 135 | D) 73 : 77 |
C) 136 : 135
Explanation:
A = 90/100*75/100
=> 0.675
B = 85/100*80/100
=> 0.68
=> 680 : 675
=> 136 : 135
A merchant sells 30 metres of cloth and gains selling price of 10 metres. Find the gain percent.
A)15% | B) 25% |
C) 50% | D) 75% |
C) 50%
Explanation:
Here, selling price of 10 m cloth is obtained as profit.
Profit of 10 m cloth = (S.P. of 30 m cloth) β (C.P. of 30 m cloth)
Selling price of 20 m cloth = Selling Price of 30 m of cloth
Let cost of each metre be Rs. 100.
Therefore, cost price of 20 m cloth = Rs. 2000 and S.P. of 20 m cloth = Rs. Rs. 3000
Profit% = 10/ 20 Γ 100 = 50%
Profit of 50 % was made by the merchant.
A dealer marks price of all the goods at 30 % above the cost price and assumes that he will make a profit of 15 % if he offers a discount of 15%. Find what will be his actual profit on sales ?
A) 15% | B) 30% |
C) 12.50% | D) 10.50% |
D) 10.50%
Explanation:
Let cost price goods be Rs. 100
Marked price (Selling Price) marked by the shopkeeper on goods = Rs. 130
He sells the goods at a discount of 15 %
Therefore,
Selling price = 85 % of Rs. 130 = Rs. 110.50
Gain = S.P. β C.P. = 110.5 β 100 = 10.50 %
Alternate solution:
He sells the goods at a discount of 15 %
15% discount on Rs. 130 = Rs. 19.50
Selling Price = Marked Price β Discount = 130 β 19.50 = Rs. 110.50
