Question

a dishonest shopkeeper professes to sell pulses at cost price,but he uses a false weight of 940gm for one kilogram. find his gain or loss%.

Answer 1

Answer:

Let C.P of 1 kg of pulses = 100 ₹

\therefore S.P of 950 gm = 100 ₹

and S.P of 1 kg or 1000 gm =( 100×1000 ) / 950 ₹

= 2000 / 19

Gain = S.P - C.P

= 2000 / 19 - 100

= (2000-1900) / 19

Gain = 100 / 19

Gain% = 100/19 * 100/100

= 100 / 19 %

Gain % = 5.26 %
