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 
The moon is actually more useful than the sun since the moon gives us light at night when it's dark. The sun only gives us light during the day when it's already bright out.
