Question

A dishonest shopkeeper uses a weight of $800gm$ for a kg and professes to sell his good at cost price. His profit is

• A. $20$%
• B. $21$%
• C. $24$%
• D. $25$%

Answer 1

The correct option is D $25$%

Let CP of $1000g$ item =Rs. $1000$
CP of $800g$ item =Rs. $800$
SP of $800g$ item =Rs. $1000$
$P$% $=\frac{1000-800}{800}\times 100$
$\frac{200}{800}\times 100=25$%
