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 Rs.6000 for the article, find the cost price of the article for A.

Let the cost price of the article for A = x rupees Then the cost price for B = x - 20°/. of x [ given that A sold at 20 percent loss to B] ⇒ x- 20x/100 ⇒ x - x/5 = 4x/5 ∴.C.P for B= 4x/5 rupees Now C.P for C = 4x/5 + 20percent of 4x/5 [ Given that B sold at 20 percent gain to C] ⇒4x/5 + 20*4x/100*5 ⇒4x/5 + 4x/25 ⇒24x/25 ∴C.P for C = 24x/25 rupees Given that C.P for C =6000 rs ∴24x/25 = 6000 ⇒24x = 6000* 25 ⇒x = 150000/24 ⇒x = 6500 rs ∴C.P for A = x = 6250 Rs

I think it is a bit confusing but if you try you would understand. I really hope you will understand.
