A shopkeeper expects a gain of 22.5% on his cost price. If in a week, his sale was of Rs. 392, what was his profit?

Rs. 18.20

Rs. 70

Rs. 72

Rs. 88.25

Answer: Option

MY FRNDS
LET CP=X....
=> SP=X+(22.5%X)
=>SP=1.225X
BUT GIVEN SP=RS 392
=>1.225X=392
=>X=320=CP
NOW PROFIT(ie CALCULATED ON CP) IMPLYING P=(392-320)=72
NO FOMULA NO DOUBT ONLY FUNDA

@anshuma

CP = (100/(100+ Gain%))*SP is a formula.

Check once all formulas regarding profit&loss. So by substitution we can get answer easily.

Anshuma Chugh said: 2 decades ago

122.5 is used by addint cost with profit,here in this formula 100/(100+22.5)*S.P we assume 100 as cost price and add 22.5 of 100 and then divide it to 100 so that ratio can be calculated and themn mutiply by any number that is S.p,r you gtng me if not then mail me at tulip_2dec@yahoo.co.in

cp=(100/(100+gain%))*sp

100+(45/2)=122.5
