Question

8) A sells an article to B at a profit of 20%. B sells it
to Cat a profit of 4%. What does it cost A if C
has paid 624?​

Answer 1

Step-by-step explanation:

A = Cost Price of A

B = Cost price of B

C = Cost price of C

B = Selling Price of A = A + (20÷100)A = A + 0.2A = 1.2A

C = Selling Price of B = B + (4÷100)B = B + 0.04B = 1.04B

Thus C = 1.04B = 1.04 × 1.2A = 1.248A = 624

Thus 1.248A = 624

Thus A = 624÷1.248

Thus A = 500 = Price at which A purchase the article.
