Answer 2

Answer:

∴ Number of people speaking English only are 57.

∴ Number of people speaking French only are 28.

∴ Number of persons who speak both English and French are 15

Step-by-step explanation:

=72+43−100

                 =15

∴ Number of persons who speak both English and French are 15

=72−15

                       =57

And  

                       =43−15

                       =28

∴ Number of people speaking English only are 57.
