    Answer : Option C

    Explanation :

    Let the amount taxable purchases be Rs. x.

     
     

    Then 6% of x = \(\frac { 30 } { 100 } \)

       

      x =  [ \(\frac { 30 } { 100 } \) x \( \frac { 100 } { 6 } \) ] = 5

     

     Cost of tax free items = Rs. [25 - (5 + 0.30)] = Rs. 19.70
