how it is loss suppose price is 100 and 5 % gain means 105 and 5 % loss means 95
so total cost price is 200 n sale price is 200 so it is loss
so total cost price is 200 n sale price is 200 so it is loss

Sanju,
Are the answer options correct?
If the 2 cost prices increased and decreased by x%,there is no loss..
Let CP=100 and X=10%
10% profit=110
10% Loss=90
Total Cp=200
Total SP=200
Loss=0% or No loss

I should have made it clear what two similar items do mean in my question. For a trader, similar items are those, which raise the same revenue when sold.pradeepkaushal9518 wrote:how it is loss suppose price is 100 and 5 % gain means 105 and 5 % loss means 95

Isn't it possible to answer it by picking few suitable set of easy going numbers for d and x and plugging those in the choices?Abhishek009 wrote:Here is the derivation just pasting the link : https://books.google.co.in/books?id=fELs ... &q&f=falsesanju09 wrote:

As we can't expect a randomly chosen test taker of knowing this formula, or going through the complex derivation part to get to it in time, hence we MUST come up with some tricks to work on the choices, though carefully.

yeh hui na baat, you picked absolutely suitable set of numbers to work with.selango wrote:Let the SP=120
x=20%
Gain of 20% Sp=120 Cp=100
Loss of 20% Sp=120 cp=150
total Sp=240 total Cp=250
Loss of 4%
Sub x=40 in options and check which one satisfy
(x/10)^2=20*20/100=4
Pick B
but why substitute 40?
