Question

55. A trader buys goods at 15/2% less than the list
price. He allows a discount of 10% on his goods.
If he wants to get a profit of 20%, at what per cent
above the list price should he mark the goods?​

Answer 1

Answer:

Let the List price(M.P) be 100 Rs.

He buys it at 15/2% off the list price

C.P = [100 - 100*(15/2)/100]

= (100 -15/2)

= 85/2

= 42.5 Rs.

P = 20%

S.P = C.P*(100+P)/100

       = 42.5*120/100

= 51 Rs.

Discount = 10%

Discount is always given on M.P

S.P = M.P*(100-discount)/100

51 = M.P*90/100

M.P = 56.7 Rs.

The (assumed) list price was 100

Hence, mark up % = (56.7-100/100) * 100 = 55.7%

So he should mark 55.7 % above the list price.

Hope it helps
