Subject :IMO Class : Class 5
If Sneha goes for Guitar classes on even number of dates only in August 20XX, then how many days
she does not go for Guitar classes? (Assume that the
4th Saturday and all Sundays are holidays.)
its wrong answer is D=12
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.
