## Answers & Explanations

1.B. The relationship can be expressed as: 15/10 =45/x; 15x = 450; x = 30.

2. C. The total amount of the bill is: 3.70/x =8/100; 370 = 8x; x = $46.25.

3. B. If E + B = 225, and E = 2B + 5, then 225 - B = 2B + 5. Solving for B, 3B = 220 and B = 73.3. 225 - 73.3 = 151.7.

4. B. Double the number that is added to the previous number. So, 4+2=6, 6+4=10, 10+8=18, 18+16=34, and 34+32=66.

5. D. 1 gallon = 128 ounces, so 8 x 128 = 1,024 ounces for 8 gallons. 1/2 = 64 gallons, and 1/4 = 32 gallons, so 64 + 32 = 96 ounces to fill the 3/4 gallons; the total ounces required is 1,024 + 96 = 1,120 ounces.

6. B. If mangoes are represented by x and coconuts are represented by y, then:

x + y = 10, and 2x + 4y = 30

2(10-y) + 4y = 30

20 - 2y + 4y = 30

2y = 10

y = 5 and x = 5, or 5 of each type of fruit

7. B. Given the increasing trend, the data can be extrapolated from 25 to about 31, the closest possible answer.

8. A. Using the Pythagorean theorem: 252 + 352 = c2. 625 + 1225 = c2. c = ?1850 = 43.01.

9. B. 20/1 =240/X. 20X = 240. X = 240/20 = 12 hours.

10. A. V = ?r2h. V = 3.14 x (32) x 12. 3.14 x 9 x 12 = 339.12.
