Correct Answer - Option 1 : Rs. 1100
Given:
Selling Price of an article is Rs. 990
Loss % = 10%
Formula used:
S.P = C.P (100 - Loss)/100
Where,
C.P = Cost Price of an article
S.P = Selling Price of an article
Calculation:
S.P = C.P (100 - Loss)/100
⇒ 990 = C.P (100 - 10)/100
⇒ C.P = 990/0.90
⇒ C.P = 1,100
∴ The cost price of an article is Rs. 1,100
