Cognizant Profit & Loss Quiz-1

Here pofit is the twice the loss
Profit = 2 Loss
SP –CP = 2 (CP – SP)
480 –CP = 2(CP – 300)
3 CP = 1080
CP= 360

Selling price=1020

loss=15%

100%-15%=85%

85% C.P =Rs.1020

C.P=1020*100/85=1200

gain%=>S.P=C.P+Profit%

100%+12%=112%

1200*112/100=Rs 1344

SP(A) = (120/100)*CP(A)
SP(B) = (125/100)*CP(B) = (125/100)*SP(A) =(125/100)*(120/100)*CP(A) --- 1
SP(B) = CP(C) = 450 -- 2
Solve 1 and 2
we get
450 = (125/100)*(120/100)*CP(A)
CP(A) = 300

Let the CP=100 with 10% loss the SP would be 90 and if it would be sold
with gain of 4% then the SP would be 104.

So the difference is 14.
But given in the question the difference is 140. So we can compare 14 units
to 140 which gives 1=10.
We have taken CP as 100 so taking 1=10 ,we get CP =100*10=1000.

Original price = 100

CP = 80

S = 80*(140/100) = 112

100 - 112 = 12%

If the cost price is Rs.100, then to get a profit of 20%, the selling price
should be Rs.120.
If 120kg is to be sold, and the dealer gives only 100kg, to get a profit of 20%.
How many grams he has to give instead of one kilogram(1000 gm).
120 gm ------ 100 gm
1000 gm ------ ?
(1000 * 100)/120 = 2500/3 = 833 1/3 grams.

15 CP = 18 SP

S.P/C.P = 15/18

gain% = ( 1 - S.P/C.P )*100

= ( 1 - 15/18 )*100

= 300/18

16.66%

That means, on selling per 11 articles he loss/profits 2.
on selling 100 articles he loss/profits( 2*100)/11= 18.18%

Let the cost price be 100%. It is sold at 10% loss. So it is sold at
90% of the cost price.
90 % of the cost price
+ 450 = 108% of the Cost price
18% of the cost price = Rs 450

Cost price of the book =
450/18 x 100 = Rs 2500

(20/100-20)=25%
25% is equivalent to 10 kg
10*4=40
100/40=2.5
the original price is 2.5 kg
