Question 1203463
------------------------------------------------------
a trader sold an article at a discount of 6% for 846. 
------------------------------------------------------



The sentence alone, stands on its own.

w, the traders article's initial value before selling it

{{{w-0.06w=846}}}

{{{0.94w=846}}}

{{{w=900}}}----------





This part totally not clear:
-------------------------------------
 if the article was initially marked to gain 20%. find the market price, cost price of the seller and discount price allowed.
