Question

A sold an article to B at a loss of 20% and B sold it to C at a gain of 20% .if C paid 6000rupees for the article, find the cost price of the article for A​

Answer 1

CP for C is SP for B

So , SP for B = ₹6000

Let the CP for B = x

Now ,

x + 20% of x = 6000

x + x = 6000

5

6x = 6000

5

6x = 6000x5

x = 6000x5

6

x = ₹5000

CP for B is SP for A

So , SP for A = ₹5000

Now,

Let CP for A = y

y - 20%ofy = 5000

y - y =5000

5

4y = 5000x 5

y = 5000x5

4

So , CP for A = ₹1250
