Question

21) In a class of 180 students, 90 students speak Bengali,
70 students speak Marathi and 50 students do NOT speak
any of these two languages. How many students speak
both the languages?​

Answer 1

Answer:

50 students do not speak

Answer 2

Step-by-step explanation:

total = 180

students who don't speak any of the two language=50

Total number of students who speaks either 180-50= 130

students who don't speak Marathi= 130-70= 60

students who don't speak Bengali= 130-90= 40

Therefore , students who speak only one language = 60+40= 100.

and students who speak both = 130-100= 30.
