Answer 1

total 45 students are in class ..

21 play chess while 23 play cards and 5 students are playing both .
it means they were counted at both place

21 + 23 -5 + non playing students = 45

39 + non playing students = 45

non playing students = 45 - 39

non playing students = 6

Answer 2

Answer:

11

Step-by-step explanation:

Total students = 45

Students play chess = 21

Students play cards = 23

5 play both the games

Students play only chess = 21-5 = 16

Students play only cards = 23-5 = 18

So, Students who do not play = 45-(16+18)=11
