conversations.value: From the 200 cookies, Javier's wife ate 30/100*200 = 60
  After the wife ate 60 cookies, the number of cookies that remained was 200-60 = 140
  The daughter also ate 40 cookies leaving 140-40 = 100 cookies.
  If Javier ate half of the remaining cookies, he ate 1/2*100 = 50.
  The number of cookies that remained is 100-50 = 50
