Profit and Loss Definition:-
Marked price(M.P): The normal price of the thing without any discount.
Cost price(C.P): The price at which an article is purchased is called its cost price.
Selling price(S.P): The price at which an article is sold is called its selling price.
Profit or Gain: If S.P>C.P, The seller is said to have a Profit or Gain.
Loss: If S.P<C.P, The seller is said to have a Loss.
Concept: Discount% always calculated on marked price. and profit% and loss% always calculate on Cost Price(C.P)
Profit And Loss Formulas
Profit or Gain= S.P-C.P
Loss=C.P-S.P
%Profit or Gain= (Profit or Gain×100)/C.P
%Loss=(Loss×100)/C.P
Concept:
Gain or Profit of x% can be represented as (100+x)/100
Loss of x% can be represented as (100-x)/100
If C.P and Profit% or Gain% given then
S.P=[C.P×(100+Gain%)]/100
If C.P and Loss’s% given then
S.P=[C.P×(100-Loss%)]/100
If S.P and Profit% or Gain% given then
C.P=(S.P×100)/(100+Gain%)
If S.P and Loss’s% given then
C.P=(S.P×100)/(100-Loss%)
Profit and Loss Formulas and important Questions
For Example:
(Q1)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 1202 (b)Rs 1190 (c)Rs 1160 (d)Rs 1000
Solution:
=>1400×(100-15)/100=S.P
=>1400×(85/100)=S.P
S.P=Rs. 1190 Ans.
(Q2)A man buys a cycle for Rs. 1400 and sells it at a profit of 20%. What is the selling price of the cycle?
(a)Rs 1500 (b)Rs 1560 (c)Rs 1580 (d)Rs 1680
Solution:
=>1400×(100+20)/100=S.P
=>1400×(120/100)=S.P
S.P=Rs. 1680 Ans.
(Q3)There is 10% loss if an article is sold at Rs. 270, then the cost price of the article is.
(a)Rs 300 (b)Rs 270 (c)Rs 320 (d)Rs 250
Solution:
=>x×(100-10)/100=270
=>x×(90/100)=270
∴ x=(270×100)/90
=Rs. 300 Ans.
BY Formula:
C.P=(S.P×100)/(100-Loss%)
C.P=(270×100)/(100-10)
=(270×100)/90
=Rs. 300 Ans.
(Q4)An item when sold for Rs. 1690 earned 30% profit on the cost price. Then the cost price is.
(a)Rs 507 (b)Rs 630 (c)Rs 1300 (d)Rs 130
Solution:
=>x×(100+30)/100=1690
=>x×(130/100)=1690
∴ x=(1690×100)/130
=Rs. 1300 Ans.
BY Formula:
C.P=(S.P×100)/(100+Profit%%)
C.P=(1690×100)/(100+30)
=(1690×100)/130
=Rs. 1300 Ans.
(Q5)A man buys an article for Rs. 27.50 and sells it for Rs. 28.60.Find his gain percent.
(a)5% (b)6% (c)4% (d)3%
Solution:C.P=Rs. 27.50
S.P=Rs. 28.60
Gain=S.P-C.P
=Rs. 28.60-Rs. 27.50
=Rs. 1.10
∴ Gain%= (Profit or Gain×100)/C.P
= (1.10×100)/27.50
= 4% Ans.
(Q6)If a radio is purchased for Rs. 490 and sold for Rs. 465.50, find the loss percent.
(a)5% (b)6% (c)4% (d)3%
Solution:C.P=Rs. 490
S.P=Rs. 465.50
Loss=C.P-S.P
=Rs. 490-Rs. 465.50
=Rs. 24.50
∴ Loss%=(Loss×100)/C.P
=(24.50×100)/490
=5% Ans.
(Q7)A fan is listed at Rs. 150 and a discount of 20% are given. Then the selling price is.
(a)Rs 180 (b)Rs 150 (c)Rs 120 (d)Rs 110
Solution:M.P=Rs. 150 Discount%=20%
Discount=150×(20/100)
=Rs. 30
S.P=M.P-Discount
=Rs. 150-Rs. 30
=Rs 120 Ans.
Another way:
=>150×(100-20)/100=S.P
=>150×(80/100)=S.P
S.P=Rs 120 Ans.
(Q8)If a Book costs Rs. 64 after 20% discount is allowed. What was its original price(i.e M.P) in Rs. ?
(a)Rs 80 (b)Rs 50 (c)Rs 75 (d)Rs 85
Solution:
=>x×(100-20)/100=64
=>x×(80/100)=64
∴ x=(64×100)/80
= Rs 80 Ans.
(Q9)A merchant purchases a table for Rs 450 and fixes its list price in such a way that after allowing a discount of 10%, he earns a profit of 20%. Then the list price of the table is.
(a)Rs 650 (b)Rs 700 (c)Rs 550 (d)Rs 600
Solution:C.P=Rs 450
Discount=10% and Profit=20%
M.P=?
=>450×(100+20)/100=S.P
=>450×(120/100)=S.P
S.P=Rs 540
=>x×(100-10)/100=540
=>x×(90/100)=540
∴ x=(540×100)/90
=Rs 600 Ans.

=86000×(125)/100
=Rs 107500 Ans.
(Q11)An Egg seller buys 240 egg for Rs. 600.Some of these eggs are bad and are thrown away.He sells the remaining egg at Rs. 3.50 each and makes a profit of 198. The percent of an egg thrown away are.
(a)6% (b)8% (c)5% (d)7%
Solution:C.P of an egg=600/240
=Rs. 2.5
profit=Rs 198
Total S.P=Profit+C.P [where Profit or Gain= S.P-C.P ]
= 198+600=Rs 798
Number of egg sold=798/3.5
=228
∴ Bad egg=240-228=12
Now,
Required percentage=(12×100)/240
= 5% Ans.

Solution:
=>x×(100+12)/100=P
=>x×(112/100)=P
112x=100P
P=112x/100
Now,
=>x×(100-4)/100=Q
=>x×(96/100)=Q
=>96x=100Q
Q=96x/100
Now,
Q/P=(96x/100)/(112x/100)
=6/7
Q:P=6:7 Ans.
(Q14)If the ratio of cost price to selling price is 10:11, Then the rate of a percent of profit is.
(a)1.1% (b)0.1% (c)10% (d)1%

(a)1:5 (b)20:21 (c)21:20 (d)5:1
Solution:
=>x×(100+5)/100=S.P
S.P=105x/100
Now,
S.P/C.P=(105x/100)/x
=21/20
∴ S.P:C.P=21:20 Ans.

Solution: By Concept And Shortcut Tricks
Profit = S.P-C.P
S.P(11m)=s.p(33m)-C.P(33m)
⇒C.P(33m)=s.p(33m)-S.P(11m)
⇒C.P(33m)=s.p(22m)
⇒C.P/S.P=22m/33m
Profit=33m-22m=11m
% Profit=(11×100)/22

C.P(11m)=C.P(33m)-S.P(33m)
⇒S.P(33m)=C.P(33m)-C.P(11m)
⇒S.P(33m)=C.P(22m)
⇒S.P/C.P=22m/33m
Loss=(33-22)m=11m
%Loss=(11×100)/33

=( 10)²/100
=100/100=1%
x×(100-1)/100=1980
x×99/100=1980
∴ x=(1980×100)/99
=Rs 2000 Ans.
(2)Loss=C.P-S.P
=Rs(2000-1980)
=Rs 20 Ans.

(Q1) A man sold two watches for Rs 525 each. On one he gains 10% and on the other he loses 15%. His profit or loss in the whole transaction is.
Solution:
=((100×-5)-2×10×15)/110+85
=(-500-300)/195
=-4.10% ie Loss=4.10% Ans.
By Concept:
100x×(100+10)/100=525
⇒ (100x×110)/100=525
∴ x=525/110
C.P of 1st watch=100x
=100×525/110
=Rs 477.27
Now,
100x×(100-15)/100=525
⇒ (100x×85)/100=525
∴ x=525/85=6.17
C.P of 2nd watch=100x
=100×6.17
=Rs 617
Now,
Total C.P=Rs(477.27+617)
=Rs 1094.27=1094
Total S.P=525+525=Rs 1050
Loss=C.P-S.P
=Rs(1094-1050)
=Rs 48
% Loss=(48×100)1094
=4.10% Ans.

TRICK-1
If two article are sold at equal prices, the first one is sold at P1% Profit and whereas the second one at a Profit of P2% And the sum of the cost price of two article is x then
For Example:
(Q1) A trader bought two watches for Rs 2300. He sold one at a profit of 10% and the other at a profit of 20%. If the selling price of each watch is the same, then their cost price are respectively.
Solution: By Trick:
C.P of watch at a profit of 10%=((100+20)/(200+10+20))×2300
=(120/230)×2300
=Rs 1200 Ans.
C.P of watch at a profit of 20%=Rs(2300-1200)
=Rs 1100 Ans.
BY CONCEPT:
Let C.P of 1st watch=x
C.P of 2nd watch=2300-x
S.P of 1st watch:
x×(100+10)/100=S.P1
11x/10=S.P1
S.P of 2nd watch:
(2300-x)×(100+20)/100=S.P2
(2300-x)×120/100=S.P2
(2300-x)×12/10=S.P2
Now According to question: selling price of each watch is the same
SO,
S.P1=S.P2
11x/10=(2300-x)×12/10
11x=2300×12-12x
23x=2300×12
x=Rs 1200 Ans
C.P of 2nd watch=2300-x
=Rs(2300-1200)
