A dishonest shopkeeper professes to sell pulses at the cost price, but he uses a false weight of 950gm. for a kg. His gain is____%.

One Answer on this Question

1. let’s say the Cost Price is 1000x. (CP)
   The selling price is also the same as the Cost price. So, here SP=CP (But he sells 950gm instead of 1000gm)

   Instead of 1000gm, he is selling 950 grams at the CP. So he sells 050 gms @1000x price. So his net profit is 50gm.
   Now 1000gm is 1000x Rs
   So, 50gms is 50x rs. [Apllied Unitary Method]

   So his profit percentage is:
   Profit Percentage Formula: {(Profit/CP)*100%}
   So, Here profit is 50x;
   CP is 1000x;
   so putting the value in the formula we get, Profit Percentage is: (50x/1000x)*100% =(5000x/1000x)%=5%.
