8. A trader buys some apples at a price of 10 apples for Rs. 8 and sold hen at a price of 8 apples for Rs. 10. Find his profit or loss %.

9. A trader allows a discount of 25% on his articles but wants to gain 50% gain. How many times the CP should be marked on the items?

10. A Trader gets a profit of 25% on an article. If he buys the article at 10% lesser price and sells it for Rs. 2 less, he still gets 25% profit. Find the actual CP of the article.



C.P of each apple = 8/10 = 0.8
S.P of each apple = 10/8 = 1.25
Profit = S.P - C.P = 1.25 - 0.8 = 0.45
Profit % = 0.45/0.8 * 100 = 56.25 %

9) Let initially C.P be 100.
He wants a profit of 50% which means C.P should be 150. But he gets that 50% after giving 25% discount. so,
x- (25x/100) = 150
75x = 150 * 100
x = 200.
So Marked Price(M.P) should be twice the C.P

10) Given S.P = 1.25 C.P -----> A
Now CP is 10% less = 0.9 C.P
S.P is 2 Rs Less = S.P - 2
Still Profit is 25% = (S.P - 2) = 1.25(0.9 C.P)
From A , S.P = 1.25 C.P by substituting
C.P = 16

11. A trader gets a discount of 20% from the dealer and marks it at 20% more price then the actual MP to the customer. Find his overall gain %.

12. A trader allows a discount of 20% to the customer after marking the item up by 25%. Find his gain/loss % if he is given a commission of 20% of the MP by the dealer.


11) Let the initial Marked price be 100. A trader gets 20% discount.
So now the price becomes 80.
He marks it at 20% more price than actual M.P = 100 + 20/100 *100 = 100+20 = 120.
Gain % = 120-80/80 *100 = 40/80 * 100 = 50%

12) Let the marked price be M.P.
S.P = 0.8 * (1.25 M.P) = M.P
C.P = 0.8 M.P
Profit = M.P - 0.8 M.P = 0.2 M.P
profit % = 0.2/0.8 * 100 = 25%

1. Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:

Solution:-

Total CP of Scooter for Alfred:-4700+800=5500 INR

Selling Price(SP)=5800 INR

Profit=5800-5500=300 INR on the Cost Pirce(CP) of 5500 INR

Therefore %age Profit is
(300/5500)*100=(3/55)*100=(3/11)*(1/5)*100=27.27*0.2=5.454 %


Please do ask if anyone needs clarification on any question

Hi All,
Thanks a lot for this SUPERB thread.It is one of the BEST things i have found here.

2.The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:

Solution:-

Let SP be the selling price of Each Article and CP be the Cost Price of each article

SP*X=CP *20
As profit is 25 % also profit is always calculated on CP,unless otherwise stated.

1.25*CP*X=CP*20

X=20/1.25=16

Therefore X=16.

3.If selling price is doubled, the profit triples. Find the profit percent.

Solution:-

Let the SP be Y and CP be X

Therefore profit is (Y-X).

When the selling price is doubled i.e. 2Y

then Profit triples=3(Y-X)

When the SP is doubled profit is (2Y-X)
which in turn is equal to 3(Y-X)

therefore:- 2Y-X=3Y-3X
Y=2X

In this problem SP will be double the CP.
Thus when SP Doubled=2X*2=4X
Original CP=X
SP Being Doubled=4X
Profit=4X-X=3X
Profit percentage=(3X/X)*100=300 %
