B19
C21
D12


its wrong answer is D=12

Ans 1:

Class : Class 5
ans is d

Ans 2:

Class : Class 6
Ans D is correct, not wrong because 2, 4, 8, 10, 12, 14, 16, 18, 22, 24, 28 and 30 are working days of guitar classes. 6 and 20 are not working days because these days are sundays and 26 is not a working day because it is a fourth saturday and even sundays and fourth saturday are not working days.

Ans 3:

Class : Class 6
Total number of days Sneha goes for guitar classes = 12∴ Number of days she does not go for guitar classes = 31 - 12 = 19

Ans 4:

Class : Class 5
