300/47%=3/47

so if i buy 47 gms of items costing 1 rs per gram i sell it at the cost of

47+3/47(47)=cost of 50 gms

so ratios between cp and sp is 47:50
940:1000

RE: Dishonest Dealer

In these type of questions,formula used is

gain%=(Error/(true value-error))*100

so 300/47=error/(True value-error)*100

3/47=error/(1000-error)

on solving u get error =60
if error is sixty that means he is using a weight of 1000-60=940gm
