Answer 1

Your question: when an item is sold at rupees 330, the gain is 10%. what is the CP of the item?

Answer:

Selling price, SP = ₹330

gain = 10%

CP = ?

gain% = (SP - CP)/CP × 100

=> 10 = (330- CP)/CP × 100

=> 10 CP= (330 - CP)×100

=> 10 CP = 33000 - 100 CP

=> 10 CP + 100 CP = 33000

=> 110CP = 33000

=> CP = 33000/110 = ₹300

CP is ₹300
