Question

018. The cost price of 36 books is equal to the selling price of 30 books. The gain is 18%​

Answer 1

Answer:

profit % = 20%

Step-by-step explanation:

Consider cost price of 36 books  = 100 rupees

Consider selling price of 30 books = 100 rupees

Calculate selling price of 36 books = (100/ 30) * 36 = 120 rupees

Now compare CP & SP of 36 books

C.P = 100 rupees

S.P = 120 Rupees

profit = 120 rupees

profit % = 20%
