Question

A sold an article to B at a profit of 2.5%. B sold the same article to Cat a loss of 10%. If
C paid 9.90 for it, how much did it cost A?​

Answer 1

Answer:

cost = 10.73

Step-by-step explanation:

Let the article be x.

With the profit of 2.5%=x+2.5x/100

With loss of 10% = = (x+2.5x/100)*10/100

=102.5x/100

Now new cost = 102.5x/ 100-102.5x/1000

=92250x/100000

=x=10.73

So cost=10.73
