Question

A dishonest shopkeeper professes to sell pulses at his cost price but uses a false weight of 950 gm for each kilogram. Find his gain percent.

Answer 1

Let cost price of 1000 gm pulses = Rs.x

But, SP of 950 gm pulses = Rs.x

∴ SP of 1000 gm pulses = 1000 x \(\frac{x}{950}\)

Gain = \(\frac{1000x}{950}\) - x = \(\frac{50x}{950}\)

Gain% = \(\cfrac{\frac{50x}{950}}{x}\) x 100 = \(\frac{100}{19}\) = \(5\frac{5}{19}\)%
