Answer 1

Answer:

Step-by-step explanation:

( 1 dozen = 12  )

cost price of 12 oranges = rs. 15

cost price of one orange = 15 / 12  = 1.25 rs

selling price of 12 orange = rs 20

selling price of 1 orange r= 20 / 12 =  1.666

1.66 rs

profit = sp - cp

profit = 1.66 - 1.25

0.41 rs .

now profit %  = sp / CP x 100

0.41 / 1.25 x 100

41 / 125  x 100

32.8 %
