Hi readers,
Yesterday I shared Profit and loss tricks. Few readers asked me to share questions with solution. Read all the Quantitative Aptitude Shortcuts here.
Q1. When a commodity is sold for Rs.34.80. there is a loss of 25%. What is the cost price of the commodity?
Ans. Option A
Ans. Option A
Let the C.P. be Rs. x.
Then x ⎯ 15 = x/16
Let the labeled
price be Rs.x. Then, 120% of x = 2880
Cost price of
all eggs = Rs.100 × 1.2 =
Rs.120
Let C.P. of
whole be Rs. x
CP of A/CP of B = 2020/1800
Charge of 1 call
in February =350/150
=
Let
the number of diaries (produced) be 100 and the cost price of a diary be Rs.1
then, total cost
incurred = 100 × 1 = 100
Let the actual
cost price of an article be Rs.1 (in place of x)
Yesterday I shared Profit and loss tricks. Few readers asked me to share questions with solution. Read all the Quantitative Aptitude Shortcuts here.
Q1. When a commodity is sold for Rs.34.80. there is a loss of 25%. What is the cost price of the commodity?
Ans. Option D
C.P. = Rs. [100/75× 34.80]
= Rs.46.40
Q2. A wheat seller sells wheat at the rate of Rs.9 per kg and thereby loses 20%. At
what price per kg, he should have sold them to make a profit of 5%?
a)
Rs.11.81 b) Rs.12 c) Rs.12.25
d)
Rs.12.31 e) None of these
Ans. Option A
85 : 9 = 105 : x
x = [9 × 105/80]
= Rs.11.81
Hence, S.P. per
kg = Rs.11.81
Q3. A merchant give 12% additional discount on the discounted price, after giving
an initial discount of 20% on the labeled price of a radio. If the final sale
price of the radio is Rs.704, then what is its labeled price?
a)
Rs.844.80 b) Rs.929.28 c) Rs.1000
d)
Rs.1044.80 e) None of these
Ans. Option C
Let the labeled
price be Rs.x
88% of 80% of x = 704
x
= [704 × 100 × 100/88
=
1000
Q4. By
selling a doll for Rs.15, a man loses one sixteenth of what it costs him. The
cost price of the doll is:
a)
Rs.16 b) Rs.18 c) Rs.20
d)
Rs.21 e) None of
these
Ans. Option A
Let the C.P. be Rs. x.
Then x ⎯ 15 = x/16
= x ⎯ x/16 = 15
= 15x/16
x = 16
Therefore, C.P. = Rs.16
Q5. Deepshikha bought a microwave oven and paid 10% less than the original price. She sold it
with 30% profit on the price she had paid. What percentage of profit did Deepshikha earn on the original price?
a)
17% b) 20% c) 27%
d)
32% e) None of
these
Let the original
price = Rs.100
Ans. Option A
Then, C.P. = Rs.90
S.P. = 130% of Rs.90 = Rs.[130/100× 90]
=
Rs.117
Required percentage = (117 ⎯ 100)%
=
17%
Q6. Saksham bought a suitcase with 15% discount on the labeled price. He sold the suitcase
for Rs.2880 with 20% profit on the labeled price. At what price did he buy the
suitcase?
a)
Rs.2040 b) Rs.2400 c) Rs.2604
d)
Rs.2640 e) None of these
Ans. Option A
Therefore x = [2880 × 100/120]
=
2400
C.P. = 85% of Rs.2400 =
Rs. [85/100× 2400]
=
Rs.2040

Q8. A
shopkeeper buys 100 eggs at Rs.1.20 per piece. Unfortunately 4 eggs got spoiled
during transportation. The shopkeeper sells the remaining eggs at Rs.15 a
dozen. Find his profit or loss?
a)
Rs.120 b) 102 c) 201
d)
121 e) None of these
Ans. Option A
Selling price of one egg =15/12
= 1.25
So, selling price of 96 eggs = 96 × 15/12
Q9. A
dealer sold three-fourth of his articles at a gain of 20% and the remaining at
cost price. Find the gain earned by him in the whole transaction.
a)
18% b) 22% c) 15%
d)
25% e) None of these
Ans. Option C
C.P. of 3/4
Total S.P. = Rs. [(120% of 3x/4
Gain = Rs.[ 23x/20⎯ x]= Rs. 3x/20
So, gain% = [3x/20× 1/x
Q10. Each

Q11. MRF charges a fixed rental of Rs.350 per month. It allows 200 calls free per month.
Each call is charged at Rs.1.4 when the number of calls exceeds 200 per month
and it charges Rs.1.6 when the number of calls exceeds 400 per month and so on.

percent the each call is cheaper in March than each call in February?
a)
28% b) 25% c) 18.5%
d)
Data inadequate e) None of these
Ans. Option A
Charge of 1 call in March =[ (350+50
=420/250
=42/25
% cheapness of a
call inn March = {7/3-42/25/(7/3)
Q12. AZAD Printers prepares diaries expecting to earn a profit of 40% by selling on the
marked price. But during transportation 8% diaries were got spoiled due to at
random rain and 32% could be sold only at 75% of the cost price. Thus the

profit or loss in the whole consignment?
a)
6% b) 10% c) 8%
d)
Data inadequate e) None of these
Ans. Option
C
Total sale price = 32 × 0.75 + 60 × 1.4 =
108
Therefore,
profit = Rs.8
Thus, there is 8% profit
Q13. ROLEX sells a wrist watch to a wholesaler making a profit of 10%. The wholesaler, in
turn, sells it to the retailer making a profit of 10%. A customer purchases it

%. What is the cost incurred by the ROLEX to produce
it?
a)
768 b) 750 c) 800
d)
820 e) None of these
Ans. Option C
[((x × 1.1) × 1.1) ×1125/1100] = 990
x = 800
Q14. A
dishonest dealer purchases goods at 20% discount of the cost price of Rs. x and
also cheats his wholesaler by getting 20% extra through false weighing, per kg.
Then he marks up his goods by 80% of x, but he gives a discount of 25% besides
he cheats his customer by weighing 10% less than the required. What is his
overall profit percentage?
a)
125% b) 100% c) 98.66%
d)
120% e) None of these
Ans. Option A
Now, he purchases goods worth Rs.120
and pays Rs.80, since 20% discount is allowed.
So, the CP =80/120
= 2/3
Again MP = 180,
SP = 135 (since 25% discount)
Thus,
the trader sells goods worth Rs.90 instead of 100 g and charges Rs.135.
Therefore the effective SP =135/90
=3/2
So, profit % = (3/2 - 2/3
Q15. A
trader mixes three varieties of groundnuts costing Rs.50, Rs.20 and Rs.30 per
kg in the ratio 2 : 4 : 3 in terms of weight, and sells the mixture at Rs.33
per kg. What percentage of profit does he make?
a)
8% b) 9% c) 10%
d)
11% e) None of these
Ans. Option C
Suppose he
bought 2 kg, 4 kg and 3 kg of the three varieties.
C.P. of 9 kg = Rs. (2 × 50 + 4 × 20
+ 3 × 30) = Rs.270
S.P. of 9 kg = Rs. (9 × 33) = Rs.297
So, profit % = [27/270× 100]% = 10%
