- Express 20 as a percentage of 80.
- A.
25
- B.
50
- C.
20
- D.
45
Correct Answer
A. 25Explanation
To express 20 as a percentage of 80, we divide 20 by 80 and then multiply by 100. This gives us 0.25, which when multiplied by 100 equals 25. Therefore, 20 is 25% of 80.Rate this question:

2. How long will a train 130 m long travelling at 40 km an hour take to pass a kilometer stone?
- A.
22.7 sec
- B.
11.7 sec
- C.
15.4 sec
- D.
11 sec
Correct Answer
B. 11.7 secExplanation
To find the time it takes for the train to pass the kilometer stone, we can use the formula:
Time=Distance/Speed
Given:
Distance (D) = 130 m
Speed (S) = 40 km/h
First, convert the speed to meters per second (since the distance is in meters): Speed=40 km/h×1000 m/1 km×1 h/3600 s
Now, substitute the values into the formula: Time=130 m/Speed
Calculate the time to pass the kilometer stone. The final result will be in seconds.
Time≈130/(40×1000/3600) s = 11.7 sec.Rate this question:

3. Find a ratio equal to 4/5 whose antecedent is 9.
- A.
4/5
- B.
5/4
- C.
45/4
- D.
10/4
Correct Answer
A. 4/5Explanation
The ratio 4/5 represents the relationship between two quantities where the first quantity is 4 and the second quantity is 5. In order to find a ratio equal to 4/5 with an antecedent (the first quantity) of 9, we need to find a ratio where the first quantity is 9 and the second quantity is a multiple of 5. Among the given options, the ratio 4/5 is the only one that satisfies this condition. Therefore, the correct answer is 4/5.Rate this question:

4. How many numbers of five digits can be formed with the digits 1,3,5,7 and 9,no digit being repeated?
- A.
125
- B.
130
- C.
120
- D.
110
Correct Answer
C. 120Explanation
To find the number of five-digit numbers that can be formed using the digits 1, 3, 5, 7, and 9 without repetition, we need to determine the number of choices for each digit. Since there are 5 digits to choose from for the first position, 4 digits for the second position, 3 digits for the third position, 2 digits for the fourth position, and 1 digit for the fifth position, we can multiply these choices together to get the total number of possibilities. Therefore, the correct answer is 120.Rate this question:

5. How many quadrilaterals can be formed by joinig the vertices of an octagon?
- A.
60
- B.
50
- C.
40
- D.
70
Correct Answer
D. 70Explanation
An octagon has 8 vertices. To form a quadrilateral, we need to select 4 vertices out of the 8. The number of ways to select 4 vertices out of 8 is given by the combination formula, which is 8C4. Evaluating this expression, we get 70. Therefore, 70 quadrilaterals can be formed by joining the vertices of an octagon.Rate this question:

6. it takes two memory locations (16 bits each) to store an address in the 8085 system?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
In the 8085 system, it actually takes three memory locations (16 bits each) to store an address, not two. This is because the 8085 system uses a 16-bit address bus, which allows it to access up to 64KB of memory. Since each memory location is 16 bits, it requires three memory locations to store a complete address. Therefore, the statement that it takes two memory locations to store an address in the 8085 system is false.Rate this question:

7. A language understood by a microprocessor is called assem.bly language?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Assembly language is a low-level programming language that is understood by humans but needs to be translated into machine code before it can be executed by a microprocessor. Therefore, the statement that "a language understood by a microprocessor is called assembly language" is false. Assembly language is a human-readable representation of machine code, not a language directly understood by the microprocessor.Rate this question:

8. A _______ is a set of computer instructions that carries out a task on the computer.
Correct Answer
ProgramExplanation
A program is a set of computer instructions that carries out a task on the computer. It is a sequence of commands and statements written in a programming language that tells the computer what operations to perform. Programs can range from simple scripts to complex software applications, and they enable computers to perform specific tasks or solve problems. Programs can be executed by the computer's processor, following the instructions step by step to achieve the desired outcome.Rate this question:
