  1. 127

  2. 135

  3. 124

  4. 144


Explanation

Let the small box and the large box are sold at x and 2x rupees respectively. Also, let weight of chocolate in small box and large box respectively is 100 gram and y gram respectively. Then

         price per gram in small box = x/100 and

         price per gram in large box = 2x/y

         As per the question,

                      = x over 100 cross times 88 over 100 space equals space fraction numerator 2 x over denominator y end fraction               = > y = 20000/88 = 2500/11 = 227
