Answer 1

Answer:

Step-by-step explanation:

students who speak in  english = 70%

students who speaks in hindi = 65%

students who doesn't speak english = 100% -70 % = 30 %

students who doesn't speak hindi = 100%  - 65 % = 35 %

Students who not speak hindi english = 30 - 27 = 3 %

                                                                  = 35 - 27 = 8%

= 3 + 8 + 27= 38%

Students who able to speak both language = 100% - 38% = 62 %
