For every X, the action [X] is defined: [X] is the greatest integer less than or equal to X. What is the value of [6.5] × [2/3] + [2] × 7.2 + [8.4] 6.6?
Show answer details
Correct answer: C
Explanation:
[6.5] × [2/3] + [2] × 7.2 + [8.4] 6.6 = 6 × 0 + 2 × 7.2 + 8 6.6 = 15.8. - 2

How many four-digit numbers that do not contain the digits 3 or 6 are there?
Show answer details
Correct answer: B
Explanation:
1st Digit can be filled up by the numbers – { 1, 2, 4, 5, 7, 8, 9 } = 7 ways 2nd Digit can be filled up by the numbers – { 0, 1, 2, 4, 5, 7, 8, 9 } = 8 ways 3rd Digit can be filled up by the numbers – { 0, 1, 2, 4, 5, 7, 8, 9 } = 8 ways So, total number of ways is 7 × 8 × 8 = 3584 - 4
The telephone company wants to add an area code composed of 2 letters to every phone number.
In order to do so, the company chose a special sign language containing 124 different signs. If the company used 122 of the signs fully and two remained unused, how many additional area codes can be created if the company uses all 124 signs?Show answer details
Correct answer: C
Explanation:
The phone company already created 122 × 122 area codes, now it can create 124 × 124.
1242 1222 = (124 + 122)(124 122) = 246 × 2 = 492 additional codes. - 5
The average (arithmetic mean) of seven numbers is 12.2. If the sum of four of these numbers is 42.8, what is the average of the other 3 numbers?
Show answer details
Correct answer: B
Explanation:
This is an average problem, so use the average formula. If the average of 7 numbers is 12.2, we can solve for their sum: 7 × 12.2 = 85.4. If four of these numbers total 42.8, then by subtracting 42.8 from 85.4, we get the sum of the other three numbers, 42.6. To find the average of these three numbers, we divide their sum by their number: 42.6/3 = 14.2. - 6
Roy is now 4 years older than Erik and half of that amount older than Iris. If in 2 years, Roy will be twice as old as Erik, then in 2 years what would be Roy’s age multiplied by Iris’s age?
Show answer details
Correct answer: C
Explanation:
Translate piece by piece into numbers. R (Roy) = E (Erik) + 4. The second equation: R = I (Iris) + 2.
The third equation: R +7 = 2(E + 7). We have three equations with three variables.
Roy is 6, Iris is 4 and Erik is 2. In four years Erik would be 6 and Iris 8, the answer is 48. - 7
An investment yields an interest payment of $228 each month. If the simple annual interest rate is 9%, what is the amount of the investment?
Show answer details
Correct answer: B
Explanation:
Principal × percent interest × time = interest earned Principal × (0.09) × 1/12 = $228.
Solve to find the principal (228 × 12) / 0.09= $30,400. - 8
X, Y, Z, and W are integers. The expression X Y Z is even and the expression Y Z W is odd. If X is even what must be true?
Show answer details
Correct answer: C
Explanation:
The first expression is even and the second is odd, the only difference between the expressions is that the first expression has X and the second has W. So, if X is even W must be odd. - 9
Q is a prime number bigger than 10. What is the smallest positive number (except 1) that 3Q can be divided by equally?
Show answer details
Correct answer: C
Explanation:
3Q is a prime number so it can be divide equally by 3Q, by 1 and by the components 3 and Q. The smallest number therefore is 3. - 10
