1. If the C.P is 90% of SP, find the gain %.
A. 10%
B. 11.11%
C. 9%
D. 10.09%
Answer
Explanation:
CP = 0.9SP
Gain = 0.1SP
Gain% = (0.1SP/0.9SP)*100 = 100/9%= 11.11%
2. Some articles were bought at 6 articles for Rs.5 and sold at 5 articles for Rs.6. Gain percent is:
A. 30%
B. 33 1/4 %
C. 35%
D. 44%
Answer
Explanation:
Suppose, number of articles bought = L.C.M. of 6 and 5 = 30.
C.P. of 30 articles = (Rs.5/6) x 30= Rs.25.
S.P. of 30 articles = (Rs.6/5) x 30= Rs.36.
Gain % = (11×25)/ 100 % = 44%.
3. A shopkeeper sells two kittens for the same price, one at a loss of 10% and the other at a profit of 10%. Find his net profit or loss in the transaction.
A. 1% Loss
B. (1/99)% Gain
C. (1 1/99 )% Loss
D. No gain, no loss
Answer
Explanation:
Let the SP of a kitten be Rs.x.
CP of the first kitten = x/0.9
CP of the second kitten = x/1.1
Total CP = 2x/0.99
Total SP = 2x CP > SP
Loss % = [[(2x/0.99)-2x]/(2x/0.99)]*100
= [(0.02x/0.99)/(2x/0.99)]*100
= 1%
4. By selling 45 lemons for Rs.40, a man loses 20 %. How many should he sell for Rs.24 to gain? 20 % in the transaction?
A.16
B.20
C.18
D.22
Answer
Explanation:
Let S.P. of 45 lemons is Rs.x.
80 : 40 = 120 : x
or, 80/40 = 120/x
or, x = 40 * 120 / 80 = 60
Lemons sold For Rs.60, = 45
Lemons sold For Rs.24, = (45/60) * 24= 18.
5. John buys a second-hand car for Rs.1,80,000 and spent Rs.20,000 for repairing it. He sold it for Rs.220,000. Find his gain %.
A. 25%
B. 20%
C. 15%
D. 10%
Answer
Explanation:
C.P = 180,000+20,000 = 200,000
S.P = 220,000
Gain %=[(220,000-200,000)/200,000] * 100 = 10%
6. The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:
A.15
B.16
C.18
D.25
Answer
Explanation:
Let C.P. of each article be Re. 1, then C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 – x).
Then, (20 – x) = (25/100 * x)
2000 – 100x = 25x
125x = 2000
x = 16.
7. A man sold 250 chairs and had a gain equal to selling price of 50 chairs. His profit percent is .
A. 5 %
B.25 %
C.10 %
D.50 %
Answer
Explanation:
Selling price of 200 chairs = cost price of 250 chairs
Let cost price of each chair is Rs 1
Cost price of 200 chairs = 200
Selling price of 200 chairs = 250
Gain % = (50/200*100) = 25%
(Since, gain = Selling price of 250 chairs – cost price of 250chairs)
Hence, Selling price of 250 chairs – cost price of 250 chairs = SP of 50 chairs
8. The gain triples when the selling price of an item is doubled. Find the gain %.
A. 100%
B. 75%
C. 50%
D. 25%
Answer
Explanation:
Let the C.P be Rs.x and the S.P be Rs.y.
Gain = y-x
2y-x = 3*(y-x)
Then, y=2x
Gain = y-x
= 2x-x
= x
Gain % = (x/x)*100 = 100%
9. 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%
Answer
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%.
10. A bought a ratio set and spent Rs110 on its repairs. He then sold it to B at 20% profit, B sold it to C at a loss’ of 10 % and C sold it for Rs.1188 at a profit of 10 %. What is the amount for which A bought the radio set?
A. Rs 850
B. Rs 930
C. Rs 890
D. Rs 950
Answer
Explanation:
110% of 90% of 120% of A = 1188.
or, [(110/100)*(90/100)*(120/100)*A] = 1188
or, A = 1188/1000
Since A =1188 hence A = 100
A purchased it for Rs.(1000 – 110) = Rs.890.
11. In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?
A.30%
B.70%
C.100%
D.250%
Answer
Explanation:
Let C.P.= Rs. 100.
Then, Profit = Rs. 320, S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 – 125) = Rs. 295.
Required percentage = (295/420)x 100 %
=1475/21%
= 70% (approximately).

= Rs. 1190
14. A man bought an article and sold it at a gain of 5 %. If he had bought it at 5% less and sold it for Re 1 less, he would have made a profit of 10%. The C.P. of the article was:
A. Rs 100
B. Rs 200
C. Rs 150
D. Rs 500
Answer
Explanation:
Let original cost price is x its cost price = 105/100 * x
= 21x/20
New Cost price = 95/100 * x = 19x/20
New Sell price = 110/100 * 19x/20 = 209x/200
[(21x/20) – (209x/200)] = 1
or, x = 200
15. A person bought 20 liters of milk at the rate of Rs 8 per liter. He got it churned after spending Rs 10 and got 5 kg of cream and 20 liters of toned milk. If he sold the cream at Rs. 30 per kg and toned milk at Rs 4 per liter, his profit in the transaction is :.
