a)30/7%
b)60/11%
c)10%
d)12%
Sol:
Cost Price(CP)=(4700+800)=5500
Selling Price(SP)=5800
If SP>CP there is profit and it is
Profit=(5800-5500)=300
%profit=(profit/CP)*100
=(300/5500)*100
=5.454545%
And value of
60/11is 5.454545 so b)60/11% is the answer.
2)If selling
price of an article is doubled, its profit triples. Find the profit percent.
a)130% b)120%
c)100%
d)300%
Sol:
Let C.P. be x and S.P. be y.
Simple profit formula=(y-x) ------------1
S.P. gets doubled=2y
New Profit = (2y - x)
Its profit gets tripled =3(y-x)
Then, 3(y - x) = (2y - x)
y = 2x.
from eq 1
hence profit=(2x-x)=x
%profit=(x/x)*100
=100%
So ans is c)100%
3) A man buys a
TV for Rs. 1400 and sells it at a loss of 15%. What is the selling price of the
TV?
a)1009
b)1060
c)1190
d)1200
Sol:
Cost Price(CP)=1400
Loss is incurred so Selling Price<Cost Price
% loss=15%
As per formula
% loss=(loss/CP)*100
15=(loss/1400)*100
15=(loss/14)
15*14=loss
210=loss
Here loss
incurred is 210
Hence Selling
Price (SP)=(1400-210)=1190
So ans is c)1190
4)Sameer
purchased 20 dozens of toys at the rate of Rs. 375 per dozen. He sold each one
of them at the rate of Rs. 33. What was his percentage profit?
a)3.5%
b)5.6% c)6.5% d)2.5%
Sol:
Cost
Price(CP)=375*20(Dozens)=7500
Total Toys=20*12(In
Dozen)=240 toys
Selling Price
(SP)=240(Toys)*33(Price of each toys)=7920
There is profit
as SP>CP
Profit=(7920-7500)=420
As per formula
%profit=(profit/CP)*100
=(420/7500)*100
=5.6%
Hence ans is
b)5.6%
5)On selling 17
pens at Rs.720, there is a loss equal to the cost price of 5 pens. The cost
price of a pen is?
a)60
b)45
c)55 d)65
Sol:
Lets consider
price of one pen is x
There is loss of
5 pens means that person sold 12(17-5) pens in 720
So Cost Price on
12 pens is 720
Price of one pen
is
x=720/12
=60
Price of one pen
is Rs.60/-
Hence ans is a)60
6)Ramesh purchased cycle for Rs. 5000 and spends Rs. 250
on its transportations. If he sells the cycle for Rs. 5075, Find his profit or
loss percentage?
a)3/7%
b)10/3%
c)10%
d)12%
Sol:
Cost Price(CP)=(5000+250)=5250
Selling Price(SP)= 5075
If SP<CP there is loss and it is
loss=(5250-5075)=175
%loss=(loss/CP)*100
=(175/5250)*100
=10/3%
=3.33%
Hence Ramesh incurred a loss of 3.33%
And value of 10/3 is 3.33% so b) 10/3 % is the answer.
7)On selling 24 pencils, Sheetal loss an amount equal to
cost price of 3 pencils. Find his loss percentage?
a)12/3%
b)50/4% c)12%
d)65%
Sol: Lets us
consider price of one pencil is Re.1
Cost price of 24 pencils=Rs.24
Loss= Cost price of 3 pencils=Rs.3
%loss=(loss/CP)*100
=(3/24)*100
=12.5%
Ans is b)50/4%, Sheetal loss percentage is 12.5%,

=320
Profit=392-320
=72
