Question

(D) {3,4}
(3) Out of 100 persons in a group, 72 persons speak English and 43 persons speak French.
Each one out of 100 persons speak at least one language. Then how many speak only
English ? How many speak only French ? How many of them speak English and French
both ?​

Answer 1

Step-by-step explanation:

Here, persons who don't speak English = 100-72= 28

and who doesn't speak french = 100-43= 57

Therefore, persons who speak only 1 language=28+57

= 85

and who speaks both = 100-85 = 15

Thus, persons who don't speak English speaks only French and those who don't speak french speaks English .
