Answer:
(a)We have, CP of 100 eggs= Rs 50.
It is given that 4 eggs were found to be broken.
So, the number of remaining eggs which were sold in the market= 100-6=94
Therefore SP of 12 eggs =Rs 8.50
Hence,SP of 1 egg=Rs 8.50/12
P of 96 eggs= Rs{8.5 X 96}/12=Rs 68
Clearly SP>CP, So, there is gain given by
Gain=SP-CP=Rs(68-50)=Rs 18
Hence,Gain %={Gain/CP}x100=(18×100)/50=36%
(c)Quicker Method:
Buy——10 for Rs 8
Sell——8 for Rs 10
Now, percenatge profit or loss is given by:
(10×10-8×8)x[100/(8×8)]=36×100/64=225/4=56.25%
Since, the sign is positive , there is a Gain of 56.25%
(a)Purchases 8 pens or Rs9
Sells 9 pens for Rs 8
%profit or loss =[8×8-9×9]x100/(9×9)=-1700/81=-20.98%
Since the sign is negative , so there is a loss of 20.98%
(b)Quicker Method:
9 16
11 20
% profit or loss=(9×20-16×11)x100(16×11)=2.27%
Since, the sign is positive , there is a Gain of 2.27%
(c)
IMPORTANT FORMULA: If the cost price of x articles is equal to the selling price of y articles , then profit percentage=(x-y)*100/y %
Applying this we get Profit=11-10)x100/10
Here retailer buys 30 pens for the certain price from a whole seller
and sells 27 pens for the same price.(Marked price as given)
Therefore, percent profit or loss=[(30-27)x100/27]=100/9%
Since,sign is positive hence there is profit.
(b)
(a)
Cost of 300 books=300×12=Rs3600
Profit = 15% of CP=15% of Rs 3600=Rs 540
SP=CP+Profit=3600+540=Rs 4140
