Question : 1 [SSC CPO S.I.2005]
If the cost price of 10 articles is equal to the selling price of 7 articles, then the gain or loss per cent is :
a) 51% gain
b) 42$6/7$% gain
c) 42$6/7$% loss
d) 35 % loss
Answer »Answer: (b)
Let C.P. of each article be Rs. 1
Then, C.P. of 7 articles = Rs. 7
S.P. of 7 articles = Rs. 10
Gain % = ${10 - 7}/7 × 100 = 300/7 = 42{6}/7%$
Using Rule 8,
Here, x = 10, y = 7
Profit % = $({x - y}/y) × 100$
= $({10 - 7}/7) × 100 = 300/7 = 42{6}/7%$
Question : 2 [SSC SO 2003]
If the cost price of 12 oranges is equal to selling price of 10 oranges, then the percentage of profit is
a) 16$2/3$%
b) 20%
c) 25%
d) 18%
Answer »Answer: (b)
Let C.P. of each orange be Rs.1
Then, C.P. of 10 oranges = Rs.10
S.P. of 10 oranges = Rs.12
Gain % = $(2/10 × 100)$% = 20%
Using Rule 8,
Here, x = 12, y = 10
Profit % = $({x - y}/y) × 100$
= $({12 - 10}/10) × 100$ = 20%
Question : 3 [SSC CHSL 2010]
Mahesh purchased a radio at $9/10$ of its selling price and sold it at 8% more than its original selling price. His gain per cent is :
a) 20 %
b) 18%
c) 8 %
d) 10 %
Answer »Answer: (a)
Using Rule 1,
If S.P > C.P. then there will be profit
Profit = S.P. - C.P.
Profit% = ${\text"Profit" × 100}/{\text"C.P."}$
Let the original selling price of radio = Rs.100
C.P. of radio = Rs.90
New selling price = Rs.108
Gain per cent = $18/90 × 100$ = 20%
Question : 4 [SSC CGL Tier-1 2011]
The selling price of 10 oranges is the cost price of 13 oranges. Then the profit percentage is
a) 30%
b) 10%
c) 3%
d) 13%
Answer »Answer: (a)
Let the CP of 1 orange = Rs.1
SP of 10 oranges = Rs.13
Gain percent = ${13 - 10}/10 × 100$ = 30%
Using Rule 8,
Here, x = 13, y = 10
Profit % = $({x - y}/y) × 100$
= $({13 - 10}/10) × 100 = 300/10$ = 30%
Question : 5 [SSC CHSL 2013]
The cost price of a book is Rs.150. At what price should it be sold to gain 20% ?
a) Rs.120
b) Rs.180
c) Rs.80
d) Rs.100
Answer »Answer: (b)
S.P. of book = ${150 × 120}/100$ = Rs.180
Using Rule 3, If an object is sold on r% Profit.
then,S.P. = C.P$[{100 + \text"Profit%"}/100]$orC.P. = S.P$[100/{100 + \text"Profit%"}]$
Similarly, If an object is sold on r% loss, then
S.P. = C.P.$[{100 - \text"Loss%"}/100]$orC.P. = S.P$[100/{100 - \text"Loss%"}]$
S.P. = C.P.$({100 + \text"Profit%"}/100)$
= ${150 × (100 + 20)}/100$
= ${150 × 120}/100$ = Rs.180
