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

Answer:

Gain percent of shopkeeper is 5

Step-by-step explanation:

The shopkeeper is using wrong weight of 950 gram against the weight of 1000 gram. It means that when is selling something to a customer for 1000 grams, he is actually giving 950 and saving 50 grams out of every 1000 grams sold. So the percentage of his saving would be;

Saving = 50 / 1000 x 100 = 5 %

Gain percent of shopkeeper is 5

Answer 2

Gain percent = $\frac{100}{19} \%$

Step-by-step explanation:

We know that,      

                      $1kg = 1000gm$

so,

Original weight $= 1000gm$

The shop keeper uses  $950 gm$ instead of $1000gm$

False weight or quantity given to customer  $= 950gm$

Difference in weights $= 1000 - 950$

                                   $= 50gm$

                         Profit in $\% = \frac{1000 - 950}{950} \times 100$

                                              $= \frac{50}{950} \times 100$

                                             $= \frac{100}{19} \%$

The shopkeeper gain $\frac{100}{19} \%$ by using false weight.
