Let the cost price (c.p.) be rupees x.

Now,selling price(S.P.) = C.P. + Profit%

Therefore,S.P. = x + 12x/100
                       => x + 0.12x

Now,according to the problem,
                                                 S.P. + 16 = 20% profit

As profit is on cost price,therefore new profit =  x + 20x/100
                                                                        => x + 0.2x

  =>  x + 1.2x + 16 = x + 0.2x
  =>  x - x + 1.2x - 0.2x = -16
  =>  -0.08x = -16
  =>   0.08x = 16
  =>   x = 200

Now, we have,  C.P. = Rupees 200
   
                         => S.P. =  x + 0.12x
                         => S.P. =  200 + (0.12) (200)
                         => S.P. =  200 + 24
                         => S.P. =  224

Hence, selling price = Rupees 224
