If a shopkeeper allows a discount of 10% to his customers and still gains 30%, then the marked price of an article which costs ₹450 is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ₹650.
Given that
The discount (D) = 10%
The profit (P) = 30%
Cost price (C.P.) = ₹450
M.P./C.P = (100 + P)/(100 - D)
M.P./450 = (100 + 30)/(100 - 10) = 130/90
M.P. = 450 × 130/90
M.P. = ₹650
