Let cp of 1 notebook be rs 100.
so therefore sp= 100*16/12
=133.33rs.
so, gain percent= 133.33-100/100*100
= 33.333333%

Answer:
     Let the Cost Price of one notebook be Rs 1.
  therefore , cost Price of 16 notebooks = Rs 16
             And Selling Price of 12 notebooks = Rs 16
                 or selling Price of one notebook = 16/12
                 therefore , Selling Price of 16 notebooks = 16/12*16
 Gain = selling Price of 16 Notebooks - Cost Price of 16 Notebooks
         =16*16/12 - 16
         =16*16 - 16*12 /12
         =16 (16 - 12)/12
         =16*4/12
         =16/3
hence gain % = Gain / Cost Price of 16 Notebooks *100
                     = (16/3)/16*100
                     =16/3*1/16*100
                    = 100/3
                    Gain %=33.33%
Hope This helps You!!

Thank You!!
