The sum of the ages of 22 boys and 24 girls is 160.What is the sum of ages of one boy plus one girl, if all the boys are of the same age and all the girls are of the same age, and only full years are counted?

  1. 5.
  2. 6.
  3. 7.
  4. 8.
  5. 9.

Answer(s): C

Explanation:

Changing the equality: 22X + 24Y = 160, we get: X=

Since X must be a positive integer, Y must be smaller than 7. The numerator will be 11, 22, 33, 44 etc. Y must be 3 and X=3. X+Y = 7. The correct answer is C.



X percents of the rooms are suits, and Y Percents of the rooms are painted light blue? Which of the following best represents the least Percentage of the light blue painted suits?

  1. X-Y.
  2. Y-X + 100.
  3. 100X-Y.
  4. X+Y-100.
  5. 100-XY.

Answer(s): D

Explanation:

D shows us the difference between the sum of the percentages and 100 percent. If X+Y>100, this percent must be subtracted from the sum X+Y in order to get 100 percent. Sum of sets minus the total equals the congruence. The correct answer is D.



David bought 13 BMW cars for a total price of 1,105,000 dollars. If he wants to make a profit of 39,000 dollars in the deal, at what price should he sell one car?

  1. 85,000$.
  2. 88,000$.
  3. 94,000$.
  4. 124,000$.
  5. 139,000$.

Answer(s): B

Explanation:

The buying price for one car is 1,105,000 / 13 = 85,000. The wished for a car is 39,000 / 13 = 3,000. So the selling price must be 85,000 + 3,000. The correct answer is B.



Loren bought a roll of cloth and sold it for a 5% profit based on the selling price. If Loren‘s profit was $45.5 total on the cloth, how much did it cost her to buy the cloth?

  2. $525.5.
  3. $675.
  4. $810.5.
  5. $864.5.

Answer(s): E

Explanation:

5% of the total price of the cloths is 45.5 dollars, multiply this number to get the entire 100% of the total selling price: (45.5 x 20 = $910). Now subtract the profit $45.5 to get the cost: 910-45.5=$864.5. The correct answer is E.
