Look at this series: 2, 1, (1/2), (1/4), ... What number should come next?
- A.
(1/3)
- B.
(1/8)
- C.
(2/8)
- D.
(1/16)
Correct Answer
B. (1/8)Explanation
The series is formed by dividing each term by 2. Starting with 2, the next term is 2/2 = 1. Then, 1/2 is obtained by dividing 1 by 2. Similarly, (1/2)/2 = 1/4, and so on. Therefore, the next number in the series should be (1/4)/2 = 1/8.Rate this question:

Look at this series: 7, 10, 8, 11, 9, 12, ... What number should come next?
- A.
7
- B.
12
- C.
13
- D.
10
Correct Answer
D. 10Explanation
The pattern in the series is that the first number increases by 3, then the next number decreases by 2, and this pattern continues alternately. Therefore, the next number should be 10, as it follows the pattern of increasing by 3.Rate this question:
-
- 3.
Look at this series: 36, 34, 30, 28, 24, ... What number should come next?
- A.
20
- B.
22
- C.
23
- D.
26
Correct Answer
B. 22Explanation
The pattern in the series is that each number is decreasing by 2, then decreasing by 4, then decreasing by 2 again. Starting with 36, we subtract 2 to get 34, then subtract 4 to get 30, then subtract 2 to get 28, and so on. Therefore, the next number in the series should be 22, as it follows the same pattern of decreasing by 2.Rate this question:
-
- 4.
Look at this series: 22, 21, 23, 22, 24, 23, ... What number should come next?
- A.
22
- B.
24
- C.
25
- D.
26
Correct Answer
C. 25Explanation
The series alternates between subtracting 1 and adding 2 to the previous number. Starting with 22, we subtract 1 to get 21, then add 2 to get 23, subtract 1 to get 22, add 2 to get 24, and so on. Following this pattern, the next number should be 25.Rate this question:
-
- 5.
Look at this series: 53, 53, 40, 40, 27, 27, ... What number should come next?
- A.
12
- B.
14
- C.
27
- D.
53
Correct Answer
B. 14Explanation
The pattern in this series is that each number is repeated twice, and then the next number is obtained by subtracting 13 from the previous number. So, starting with 53, the next number should be obtained by subtracting 13 from 40, resulting in 27. Therefore, the number that should come next is 27.Rate this question:

Look carefully for the pattern, and then choose which pair of numbers comes next.Which one do you like? 28 25 5 21 18 5 14
- A.
11 5
- B.
10 7
- C.
11 8
- D.
5 10
- E.
10 5
Correct Answer
A. 11 5Explanation
The pattern in the given sequence is as follows:
The first number in each pair is obtained by subtracting 3 from the previous number, and the second number is obtained by subtracting 7 from the previous number.
Starting with 28, we subtract 3 to get 25, then subtract 7 to get 18, and so on.
Therefore, the next pair of numbers would be 11 (obtained by subtracting 3 from 18) and 5 (obtained by subtracting 7 from 25).Rate this question:
-
- 7.
What number should come next? 8 11 21 15 18 21 22
- A.
25 18
- B.
25 21
- C.
25 29
- D.
24 21
Correct Answer
B. 25 21Explanation
The pattern in the given sequence is not consistent, making it difficult to determine the exact rule. However, if we analyze the sequence, we can observe that the numbers increase and decrease alternately. The first number increases by 3 (8+3=11), then the second number increases by 10 (11+10=21), then the third number decreases by 6 (21-6=15), and so on. Following this pattern, the next number should increase by 3, resulting in 25. For the second number, it decreases by 3, so the next number should be 21.Rate this question:

Senators from urban areas are very concerned about assuring that there will be funding for a new international airport. Senators from rural areas refuse to fund anything until money for agricultural subsidies is appropriated. If the legislature funds these two programs, on which of the following could they spend the rest of the money?
- A.
The school music program and national radio
- B.
Hurricane preparedness
- C.
Harbor improvements and the school music program
- D.
Small business loan program
- E.
National radio and senate office building remodeling
Correct Answer
A. The school music program and national radioExplanation
Given that senators from urban areas are concerned about funding for a new international airport and senators from rural areas refuse to fund anything until money for agricultural subsidies is appropriated, it can be inferred that the legislature has already allocated funds for these two programs. Therefore, they can spend the rest of the money on other programs such as the school music program and national radio.Rate this question:

Which of the following statements should be used to obtain a remainder after dividing 3.14 by 2.1 ?
- A.
Rem = 3.14 % 2.1;
- B.
Rem = modf(3.14, 2.1);
- C.
Rem = fmod(3.14, 2.1);
- D.
Remainder cannot be obtain in floating point division
Correct Answer
C. Rem = fmod(3.14, 2.1);Explanation
The correct answer is "rem = fmod(3.14, 2.1);" because the fmod() function in C++ returns the remainder of dividing the first argument by the second argument. In this case, it will return the remainder after dividing 3.14 by 2.1.Rate this question:

By default a real number is treated as a
- A.
Float
- B.
Double
- C.
Long double
- D.
Far double
Correct Answer
B. DoubleExplanation
A real number is treated as a double by default because double is a data type that can store a larger range of values with higher precision compared to float. Double uses 8 bytes of memory to store the value, allowing it to represent a wider range of numbers with greater accuracy. Therefore, when a real number is not explicitly specified with a data type, it is assumed to be a double by default.Rate this question:

Is the following statement a declaration or definition? extern int i;
- A.
Declaration
- B.
Definition
- C.
Function
- D.
Error
Correct Answer
A. DeclarationExplanation
The given statement "extern int i;" is an example of a declaration. In C programming, the "extern" keyword is used to declare a variable without defining it. It tells the compiler that the variable "i" is defined in another file or module. This allows multiple files to share the same variable. Therefore, the statement is a declaration.Rate this question:

Which word does NOT belong with the others?
- A.
Evaluate
- B.
Assess
- C.
Instruct
Correct Answer
C. InstructExplanation
The word "instruct" does not belong with the others because it does not involve the process of analyzing or evaluating something. "Evaluate" and "assess" both refer to the act of assessing or judging the value or quality of something, whereas "instruct" means to give directions or guidance on how to do something. Therefore, "instruct" is the odd one out in this group.Rate this question:

If a - b = 3 and a2 + b2 = 29, find the value of ab.
- A.
10
- B.
12
- C.
15
- D.
18
Correct Answer
A. 10Explanation
Given that a - b = 3 and a^2 + b^2 = 29, we can use the formula (a - b)^2 = a^2 - 2ab + b^2 to find the value of ab. Expanding the formula, we get a^2 - 2ab + b^2 = 9. Subtracting this equation from a^2 + b^2 = 29, we get 2ab = 20. Dividing both sides by 2, we find that ab = 10. Therefore, the value of ab is 10.Rate this question:

- A.
10
- B.
12
- C.
15
- D.
18
Correct Answer
A. 10Explanation
Given that a - b = 3 and a^2 + b^2 = 29, we can use these equations to solve for the value of ab.
We can square the equation a - b = 3 to get (a - b)^2 = 9. Expanding this, we get a^2 - 2ab + b^2 = 9.
Now, we can substitute the value of a^2 + b^2 from the second equation into this equation.
So, we have a^2 - 2ab + b^2 = a^2 + b^2 = 29.
Simplifying this equation, we get -2ab = -29. Dividing both sides by -2, we find that ab = 29/2.
Therefore, the value of ab is 10.Rate this question:

The product of two numbers is 120 and the sum of their squares is 289. The sum of the number is:
- A.
20
- B.
23
- C.
169
- D.
None of above
Correct Answer
B. 23Explanation
Let the two numbers be x and y. We are given that the product of the two numbers is 120, so we have the equation xy = 120. We are also given that the sum of their squares is 289, so we have the equation x^2 + y^2 = 289. We can solve these equations simultaneously to find the values of x and y. By trial and error, we find that x = 15 and y = 8 satisfy both equations. Therefore, the sum of the numbers is 15 + 8 = 23.Rate this question:

An error 2% in excess is made while measuring the side of a square. The percentage of error in the calculated area of the square is:
- A.
2%
- B.
2.02%
- C.
4%
- D.
4.04%
Correct Answer
D. 4.04%Explanation
When measuring the side of a square, an error of 2% in excess is made. This means that the measured side is 102% of the actual side. The area of a square is calculated by squaring its side length. Therefore, the error in the calculated area can be found by squaring the error in the side length. In this case, squaring 2% gives an error of 4.04%. So, the percentage of error in the calculated area of the square is 4.04%.Rate this question:
