Profit Loss Class 7 RS Aggarwal Goyal Brothers ICSE Foundation Maths Solutions
Question: 1- Amit bought a calculator for RS 960 and sold it for 1104.Find his gain and gain percent.
Solution: C.P. = 960, S.P. = 1104
Gain = S.P-C.P.
= 1104-960=144
Gain%=Gain*100/C.P
=144*100/960
Gain%= 15% Ans
Question: 2- Ankita bought a mobile phone for RS 2350 and sold it for RS 2538. Find her gain and gain percent.
Solution: C.P.=2350, S.P.=2538
Gain=S.P.-C.P.
=2538-2350=188 Ans
Gain%=Gain*100/C.P.
=188*100/2350
Gain%= 8% Ans
Question: 3- Ayush bought a bicycle for RS 6250 and had to sell it for RS 5875. Find his loss and loss percent.
Solution: C.P.=RS 6250, S.P.=RS 5875
Loss=C.P.-S.P.
=6250-5875
=375 Ans
Loss%=Loss*100/C.P.
=375*100/6250
Loss%= 6% Ans
Question: 4- Aman bought a computer for RS 24000 and its accessories pack worth for RS 1750. He sold it all for RS 26780. Find his gain and gain percent.
Solution: C.P. of computer = RS 24000
C.P. of accessories = RS 1750
Total C.P. = 2400+1750=25750
S.P.= RS 26750
Gain = S.P.-C.P.
= 26780-25750
= 1030 Ans
Gain% = Gain*100/C.P.
= 1030*100/25750
Gain% = 4% Ans
Question: 5- A man bought a refrigerator for RS 35615 and paid RS 125 on its transportation. He sold it for RS 33953. Find his gain or loss percent.
Solution: C.P of refrigerator = RS 35615
C.P. of transportation = RS 125
Total C.P. = 35615+125
=RS 35740
S.P. = RS 33953
Loss = C.P.-S.P.
= 35740-33953
= RS 1787
Loss% = Loss*100/C.P.
1787*100/35740
Loss% = 5% Ans
Question: 6- By selling a bicycle for RS 5670 a trader gain RS 270. Find his gain percent.
Solution: S.P. = RS 5670, Gain = RS 270
C.P. = S.P.-Gain
=5670-270=5400
Gain% = 270*100/5400
Gain% = 5% Ans
Question: 7- By selling a chair for RS 1410 a carpenter suffers a loss of RS 90. Find his loss percent.
Solution: S.P. = RS 1410, Loss = RS 90
C.P. = S.P.+ Loss
=1410+90
=1500
Loss% = 90*100/1500
Loss% = 6% Ans
Question: 8- A fruit-seller bought bananas at the rate of 3 for RS 8 and sold them at the rate of 2 for RS 7. Find his gain and loss percent.
Solution: Rate of 3 bananas = RS 8
Lost price of banana = RS 8/3
S.P. of 2 bananas = RS 7
S.P. of 1 banana = RS 7/2
Gain = 7/2 – 8/3 = 5/6
Gain% = (5/6 * 100) / (8/3) =125/4%
=31(1/4)%.
Question: 9- Lemons are bought at the rate of 3 for RS 4. At what rate must they be sold to gain 20%.
Solution: Cost price of 3 lemons =RS 4
Gain = 20%
S.P. of 3 lemons = 4 * 120/100
= RS 24/5
C.P. of 1 lemon = 24/5*3
= RS 8/5
S.P. of 5 lemons = 8/5 *5 = RS 8
5 lemons are sold for RS 8. Ans
Question: 10- The selling price of 12 pens is equal to the cost price of 14 pens. Find his gain percent.
Solution: C.P. of 12 pens = RS 12
Let C.P. of 1 pen = RS 1
S.P. of 12 pens = C.P. of 12 pen
=RS 14
Gain = S.P.-C.P.
=14-12 = RS 2
Gain% = Gain*100/C.P.
= 2*100/12 = 50/3% Ans.
Question: 11- The cost price of 12 oranges is equal to the selling price of 15 oranges. Find his loss percent.
Solution: Let C.P. of 1 orange = RS 1
C.P. of 15 oranges = C.P. of 12 oranges
= RS 12
Loss = C.P.-S.P.
=15-12 = 3
Loss% = Loss*100/C.P.
= 3*100/15 = 20% Ans.
Question: 12- Vinay sold a plot of land for RS 143000, gaining 4%. For how much did he purchase a plot?
Solution: S.P. of plot = RS 143000
Gain = 4%
C.P. of a plot = RS 100/100+Gain% * S.P.
= 100/100+4 * 143000
= 100/104 * 143000
Hence 100*1375 = RS 137500 Ans.
Question: 13- John sold his T.V. set for RS 14100, losing 6%. For much did he purchase it?
Solution: S.P. of T.V. set = RS 14100
Loss = 6%
C.P. = RS 100/100-Loss * S.P.
C.P. of set = RS 100/100-6 * 14100
= 100/94*14100
C.P. = RS 15000 Ans.
Question: 14- On selling a bed for RS 10800, a carpenter loses 10%. For what amount should he sell it to gain 5%?
Solution: S.P. of bed = RS 10800
Loss = 10%
C.P. of bed = S.P.*100/100-Loss
= 10800*100/100-10 = 12000
C.P. of bed = RS 12000
Gain = 5%
S.P. = RS 100+Gain%/100 * C.P.
= RS 12000(100+5)/100
S.P. = RS 12600 Ans.
Question: 15- On selling an almirah for RS 20350, a man gain 10%. What percent does he gain on selling the same for RS 19610?
Solution: S.P. of almirah = RS 20350
Gain = 10%
C.P. = S.P.*100/(100+Gain%)
= 20350*100/100+10
= RS 18500
When S.P. = 19610
Gain = S.P.-C.P.
= RS 19610-18500
= RS 1110
Gain% = total gain*100/C.P.
= 1110*100/13500
Gain = 6% Ans.
Question: 16- On selling a fan for RS 4700, a shopkeeper loses 6%. At what price must he sell it to gain 6%?
Solution: S.P. of fan = RS 4700
Loss = 6%
C.P. = 100/100-Loss% * S.P.
= 100/(100-6)*4700
= 100/94*4700
Hence RS 5000
IF Gain = 6%
S.P. = RS (100+6)/100*5000
= 106/100*5000
S.P. = RS 5300 Ans.
Question: 17- Kamal sold two scooters for RS 19800 each, gaining 10% on the one and losing 10% on the other. Find his gain or loss percent on the whole transactions.
Solution:
The one sold at a gain we have :
100/110 × 19800 = 18000
buying price = 18000
The one sold at a loss we have :
100/90 × 19800 = 22000
The overall buying price for the two is :
22000 + 18000 = RS 40000
The overall selling price for the two is :
19800 × 2 = 39600
The selling price is lowered than the buying price by :
40000 – 39600 = RS 400
There is therefore a loss of 400
The percentage loss is thus :
400/40000 × 100% = 1% loss Ans.
Question: 18- A buys an article for RS 650 and sell it to B at a profit of 20%. B sell it to C at a loss of 20%. What does C pay for it?
Solution:
Cost price when “A” buys an article = 650
Sells it to “B” at Profit Percentage = 20 % .
Selling Price = Cost Price + Profit
= 650 + (650 x 20%)
= 650 + 130
=Rs 780 .
So , “A” sells it to “B” at Rs 780 .
Cost Price when “B” buys an article = 780
Loss % = 20 %
Selling Price = Cost Price – Loss
= 780 – (780 x 20%)
= 780 – 156
Hence Rs 624 .
So , “B” sells it to “C” at Rs 624 .
Cost Price when “C” buys an article = Rs 624.
“C” PAYS FOR AN ARTICLE = Rs 624 Ans.
