An article was sold at a gain of 18%. If it had been sold for ₹ 49 more, then the gain would have been 25%. The cost price of the article is:

₹ 700

Profit₁% = 25

Profit₂% = 18

Direct concept = Profit₁% - Profit₂% = Given profit in rupees

                          25%  -  18%   = 49

                            7% of CP = 49

                          100% of CP = 700
