1.

a dishonest shopkeeper sells his grocery using weights 10% less than true weight and makes a profit of 30% . find his total gain percent​

Answer»

Let the COST of 1- Kg of a goods be = Rs 100. If he earns a profit of 30%, he should sell the goods weighing 1- Kg (1000- g) for Rs 130.

Since he is a dishonest shopkeeper, he SELLS 900- g (0.9- Kg) of his goods as 1- kg for Rs 130.

So the ACTUAL profit percentage is

= (130–90)/90 x 100

= 40/90 x 100

= 44.44%
