Dear friends,

Can anyone of u ,help me to solve this problem..?

Also plz explain me "wats profit on selling price"...?

Qn:

Two merchants sell, each an article for Rs.1000. If Merchant A computes his profit on cost price, while Merchant B computes his profit on selling price, they end up making profits of 25% respectively. By how much is the profit made by Merchant B greater than that of Merchant A?

Profit on SP means the percentage of profit is calculated with respect to sales price

i.e ** % of profit = ( profit amount / sales price ) x 100 **

Profit on CP means the percentage of profit is calculated with respect to cost price

i.e** % of profit = (profit amount / cost price ) x 100
**

and profit amount = sale price – cost price

=================================================================

For Merchant A : Profit is on CP ,Profit= 25% and SP=1000

i.e (1000-CP)/CP x 100 = 25

=> 1000 –CP = CP/4

=> 5/4 CP = 1000

=>CP = 800

Profit= 200

For Merchant B : Profit is on SP ,Profit= 25% and SP=1000

i.e [(1000-CP)/1000] x 100 = 25

=> 1000 –CP = 250

=> CP = 750

Profit = 250

So the answer is Rs. 50 that is the profit made by merchant B is Rs.50 more than merchant A

I have not understood your **case2 and case3**.I solved the question in foll manner:

Case1)Solved in same manner as u did.

Case2)C.P.for 1Kg is 100 so for 800gm will be 80

S.P.is 100.So profit will be 20%

Case3)C.P.is 80 and S.P. is 100.So profit will be 20%

Case4)Solved it in same manner as you did.

So answer I got is Profit is same for all.

For case 2 you can apply this formulae:

(100+gain%)/100=True Scale Reading/False scale reading..This will give you gain% of 25%.

if a product sells25%discount he get 25%profit if he sells 10%discount how much profit he will get?

a certain brand of soap powder is sold at Rs 8.50 per packet. It costs Rs 85.00 a dozen. What is the gain or loss per cent on 5 dozen packet?

IS IT 16.66% ?

IS IT 16.66 % ?

Case 1 : CP = 100 SP=120 profit Rs.20 or 20%

Case 2: CP =100 for 1 kg then 80 for 800g

And here he will be selling at Rs.100

So profit=(100-80)/80 => 25%

Case 3: CP=100 for 1.2 kg

=> CP for 1 kg = (100/1.2)=83.33

SP=100 for 1 kg

So profit (100-83.3)/83.3 = 16.6/83.3 i.e 19.92 %

Case 4: CP

_{1}=100 SP= 110And CP for 1kg = 100

CP for 900g = 90

So profit = 20%

Thus case 2 is the answer
