Question

Amar brought 4 dozen pencil at rs.7.20 rs.a dozen and sold them for 20 paise each .find his gain or profit percent.​

Answer 1

Step-by-step explanation:

1 dozen = 7.20 rs

4 dozen pencil cost = 4×7.20

=28.80

1 dozen is equal to 12

so 4 dozen value = 4×12=48

sold them each 20 paiSe

so selling price = 20×48=960 paise= 9.60rs

here cost price is more then selling price so we get loss.

loss= cost price -selling price

28.80-9.60=19.20rs

$loss \: percentage = \frac{loss}{cost \: price} \times 100$

$\frac{19.20}{28.80} \times 100$

loss percentage=66.66%
