A vendor marks his goods at such a price that he can give a discount of 24% for cash payment and yet make 20% profit. Find the market price of an item which cost him Rs. 275.50.

A Rs. 418.25

B Rs. 420.75

C Rs. 435

D Rs. 400

E Rs.  400.75

Solution

Correct Answer: Option C

Let the Marked Price(M.P.) of the item be Rs.x.

Price after a discount of 24% = x – (24% of x) = x – 0.24x = 0.76x

Profit % = \(\frac{{S.P. - C.P.}}{{C.P.}} \times 100\)

⇒ 20 C.P. = 100 × (0.76x – C.P.)

⇒ 20 C.P. + 100 C.P. = 76x

⇒ 120 C.P. = 76x

⇒ 120 × 275.50 = 76x

⇒ x = 435

∴ Marked price of the item =Rs. 435
