A dishonest dealer claims to sell his goods for the cost price. If he uses 20% less weight in weighing the goods, his gain % is:
Let say ,he was selling 100 weight of products and cost price of the product c.
So,he was actually selling 0.8×100=80 weight of products.
80 unit were selling for c Rs.
1unit was selling for c/80 Rs.
So, 100 units were selling for (100/80)c
=1.25c Rs.
So, his overall gain was=((1.25c-c)/c)×100
=25%.
C is correct choice.
