Answer 1

Something alike:

def calculate_dates
    self.openedon = Date.today
    case self.noy
    when '1'
      self.md = self.openedon+1.year
    when '2'
      self.md = self.openedon+2.years
    when '3'
      self.md = self.openedon+3.years
    when '4'
      self.md = self.openedon+4.years
    when '5'
      self.md = self.openedon+5.years
    else
      self.md = self.openedon+6.months
    end
end

Rails has quite easy-to-use date operators:

Date.parse('13/05/2013') + 1.year
# => Tue, 13 May 2014
Date.parse('15/09/2012') + 2.years
# => Mon, 15 Sep 2014 

Same for 6.months, etc.
