Answer :
     Let the number of ten rupee notes = x
  therefore , number of five rupee notes = x+3
   Total money = 10*(number of ten rupee notes ) + 5 (number of five rupee notes)
                     = 10*x + 5*(x+3)
                     =10x +5x +15
                     =15x + 15
therefore ,
           15x+15 = 195
           15x = 195 - 15
            15x = 180
             or x = 180/15
                     x=12
Therefore number of ten rupee notes = 12
hence , number of five rupee notes = x+3
                                                         =12 + 3
                                                         =15

Hope this helps you!!
