A Dishonest Shopkeeper Professes To Sell Pulses At His Cost Price But Uses A False Weight Of 950 Gm For Kilogram. Thus His Gain Percent Is A B/C%.

Sol:

A shopkeeper sells 950 gm pulses and gets a gain of 50 gm

\( \Rightarrow (1000 gm−950 gm) \)

If a shopkeeper sells 100 gm of pulses, he will gain

\( \Rightarrow [\frac{Error}{(True value) – (Error) * 100}]% \) \( \Rightarrow [\frac{50}{(1000) – (50) }* 100]% \) \( \Rightarrow \frac{5000}{950}% \) \( \Rightarrow \frac{100}{19}% \) \( \Rightarrow 5\frac{5}{19}% \)

Therefore, his gain percent is \( 5\frac{5}{19}% or \frac{100}{19}% \)
