You can put this solution on YOUR website! The percent profit made when an article is sold for Rs.78 is twice as when it is sold for Rs. 69.The cost price of the article is ?
----------------
Profit = Revenue - Cost
---------
Equations:
2p = 78 - C
p = 69 - C
-----------------
p = 9
----
Substitute into p = 69 - C to get:
9 = 69 - C
Cost = 60Rs
