Let the price of pens be "x" instead of one rupee.
Cost Price (C.P) of 12pens = 12x
Selling Price (S.P) of 9pens = 9x
C.P = S.P
12x = 9x
This can be written as,
S.P = C.P
12x = 9x
Gain = 12x - 9x = 3x
Gain% = Gain/C.P*100 = 3x/9x*100 = 33.33%

Avish25: Your answer is wrong
Avish25: It is gain
sethuraman464osxp20: For example, If you bought 10 pens for ₹100, then if u sell the same 10 pens for ₹50, it is loss only. Likewise the same sum u asked
sethuraman464osxp20: Sorry, i didn't read the question correctly, I'll change the ans
Avish25: Plz change
sethuraman464osxp20: ok
sethuraman464osxp20: Now i changed the answer into correct
Avish25: Thanks
