Question

A shopkeeper earns a loss of 5% but he gains 5% if he uses the false weight what is the actual weight

Answer 1

Answer:

   Sale Price= C.P x 0.95 x 1000/W.

   If “W” - is the weight of the antique stones, then the Sale Price will be 1.05- times C.P.

   So C.Px 1.05 = C.P x 0.95 x 1000/W

   So W= 0.95/1.05 x 1000

   W = 904.75-

   W ≈ 905- g

   So if the shopkeeper sells stones with weight 905- g as 1- kg, he will get a profit of 5%, even if he reduced the COST PRICE by 5% .
