the contribution for a picnic was 65 rupees each altogether 2900 and 25 rupees were collected how many had collected for picnic.com

Dear Student, 

   Total amount collected for the Picnic = Rs 2925
   Amount paid by each = Rs 65

  So, Number of people who paid the amount = 2925/65
                                                                        = 45
  Hence 45 People paid the Rs 65 each which totalled to Rs 2925.

Hope this information clears your doubts.

Regards
