Answer 1

Second method to solve this question :

Here, C.P. = Rs. 80, M.P. = Rs. 120, D = 40%

Using the given formula ,

M.P.= 100 + r

C.P. 100 − D120=

100 + r80 100 − 403=

100 + r2 60

90 = 100 + r

r =–10% (–ve sign shows loss)

⇒ Loss = 10%

Answer 2

Given that , CP of article = ₹ 80 and marked price = ₹ 120

Discount = 120 ×40= ₹ 48100

Loss = 80 – 72 = ₹ 8
