Question

Ashish bought some rulers at the rate of ₹180/dozen. He sold them for Rs. 24 each. His profit percentage is ______%.​

A.

58

B.

60

C.

62

D.

64

Correct option is B

Given:

Cost price of rulers = Rs. 180 per dozen

Selling price of one ruler = Rs. 24

Find the profit percentage.

Formula Used:

Profit % = ProfitCost Price×100\frac{\text{Profit}}{\text{Cost Price}} \times 100​​

Solution:

Cost price of 1 dozen (12 rulers) = Rs. 180

Cost price per ruler = 18012\frac{180}{12}​ = 15

Selling price per ruler = Rs. 24

Profit per ruler: 24 - 15 = 9

Profit percentage: 915×100\frac{9}{15} \times 100​ = 60%
