Hey Bump, Denise has been teaching me some of her top secret intelligience tricks... how's my score lookin here:
1. 28 gallons.
Twenty four-gallon cans = 80 gallons x ½ = 40 gallons
Twenty-four gallon cans = 24 gallons x ½ = 12 gallons
Difference = 28 gallons
2. Rasputin
3. 7 days
Total effort required by 4 painters for 45 days = 4 x 45 = 180 man-days
Initial effort by 4 painters for 10 days = 4 x 10 = 40 man-days
Job still requires 180-40 = 140 man-days, and there are 20 painters available to do it.
Completing the project requires 140 man-days ÷ 20 painters = 7 days
4. Brazil
5. Beth is 6, Jo is 22
6. Agent 43
7. 100 nails
The four corners of the scale have one nail each. Each side of the square now requires 24 nails. (Excluding the four corners). Thus, the total number of nails required would be 4 + (4 x 24) = 100 nails
8. None
9. 89
Total marks in 10 subjects = 10 x 82 = 820
Total marks in two English subjects = 2 x 54 = 108
Total marks in eight remaining subjects = 820 - 108 = 712
Average mark in remaining 8 subjects = 712 ÷ 8 = 89
10. Rosalynn Carter’s
