Question

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

Answer 1

Answer:

Step-by-step explanation:

Let article =x

With 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 = 9.9

X= 10.73

So cost of article A = 10. 73
