Answer :

Total Players (x)       Players who prefer pizza (y)
  10                                              7                                          
  20                                             14
  40                                             28
  80                                             56
  120                                           84
 
 84 students would prefer pizza over Chinese   

If 7/10 prefer pizza, then 70% prefer pizza. This means only 30% prefer chinese food.
