6. I get two dozen
A hen and a half make an egg and a half in a day and a half which works out to 6 eggs in 6 days. Since a half dozen hens is 4 times the number of a hen and a half, the number of eggs made in six days would be 4x6 or 24
Did you ever stop to think and then forget to start again?

4. 101% (a+b+c)/3 = 73 so a+b+c = 219 (a+b+c+d)/4 = 80 so a+b+c+d = 320 d = 101
Netflix needs to stop asking if I'm still watching and start asking if I've switched the laundry over yet
