- C.
Increasing volume of CO2+CH4
- D.
Increasing volume of CH4
Correct Answer
C. Increasing volume of CO2+CH4Explanation
The increasing volume of CO2 and CH4 is responsible for the Greenhouse Effect. These gases trap heat in the Earth's atmosphere, leading to a rise in global temperatures. CO2 is released through the burning of fossil fuels, deforestation, and industrial processes. CH4, also known as methane, is emitted from natural sources like wetlands and livestock, as well as from human activities such as agriculture and the production of coal, oil, and gas. The accumulation of these gases in the atmosphere enhances the greenhouse effect, causing climate change and its associated impacts.Rate this question:

Computer is not being used in education as
- A.
An equipment
- B.
An interactive teaching tool
- C.
A management tool
- D.
An assessment
Correct Answer
D. An assessmentExplanation
The computer is not being used in education as an assessment because it is not being utilized to evaluate or measure the learning progress or outcomes of students. While computers can be used for various educational purposes such as equipment, interactive teaching tools, and management tools, they are not typically employed as a means of assessment in education. This suggests that other methods or tools are being used for evaluating students' knowledge and performance.Rate this question:

Which are not the computer sub-systems?
- A.
Software
- B.
Hardware
- C.
Applicationware
- D.
Humanware
Correct Answer
C. ApplicationwareExplanation
Applicationware is not considered a computer sub-system because it is not a physical component or part of a computer system. Software, hardware, and humanware are all sub-systems of a computer. Software refers to the programs and operating systems that run on the hardware. Hardware refers to the physical components of a computer system, such as the processor, memory, and storage devices. Humanware refers to the human users and their interactions with the computer system. However, applicationware is not a recognized term in the field of computer systems and is not considered a sub-system.Rate this question:

Correct Answer
C. Collection ErrorsExplanation
Collection errors refer to mistakes or inaccuracies that occur during the process of collecting data. These errors can include issues such as recording incorrect information, omitting data, or using faulty measurement instruments. Measurement errors, on the other hand, pertain to inaccuracies in the actual measurement or observation of the data. Therefore, the given answer of "Collection Errors" is correct as it specifically addresses errors that occur during the data collection process, rather than errors in measurement.Rate this question:

A table has been provided below on the scores given in three different sets on different times to students ClassSet ISet IISet III16165003002711720511389898867847406124505421533250681284461475215413418781777551969875644810701676305In respect of the scores, which of the following is true?
- A.
All sets are inter-linked.
- B.
Set I and II explains positive relationships.
- C.
Set II and III are inter-linked.
- D.
None of the above.
Correct Answer
B. Set I and II explains positive relationships.Explanation
The given table shows the scores given in three different sets on different times to students. By comparing the scores in Set I and Set II, it can be observed that as the scores in Set I increase, the scores in Set II also increase. This indicates a positive relationship between the two sets. However, there is no clear relationship between Set II and Set III, as the scores in Set III do not follow a consistent pattern with the scores in Set II. Therefore, the correct answer is "Set I and II explains positive relationships."Rate this question:

Instructions: The next two questions (11-12) consist of a question and two statements with the number I & II. You need to decide whether the data provided in statements are enough to answer the question.Read both the statements in the next two questions and give the answerHow A is related to B?
- B says, “I have only one brother”.
- A says, “I have only one sister”.
- A.
If the data in statement II alone are sufficient to answer, while the data in statement I alone are not sufficient to answer the question
- B.
If the data in statement I alone are sufficient to answer, while the data in statement II alone are not sufficient to answer the question
- C.
If the data either in statement I alone or statement II alone are not sufficient to answer the question; and
- D.
If the data either in statements I and II together are not sufficient to answer the question
Correct Answer
D. If the data either in statements I and II together are not sufficient to answer the questionExplanation
The given answer suggests that neither statement I nor statement II alone is sufficient to answer the question of how A is related to B. It also implies that the data in both statements I and II together are not sufficient to answer the question. Therefore, additional information is needed to determine the relationship between A and B.Rate this question:

- D.
If the data either in statements I and II together are not sufficient to answer the question
Correct Answer
A. If the data in statement II alone are sufficient to answer, while the data in statement I alone are not sufficient to answer the questionExplanation
The question is asking for Rishabh's birthday this year. Statement I provides the information that Rishabh's birthday is between January 13 and 15, with January 13 being a Wednesday. However, this information alone is not sufficient to determine the exact date of Rishabh's birthday. Statement II states that Rishabh's birthday is not on Friday. This information alone is enough to determine the exact date of Rishabh's birthday, as it eliminates Friday as a possibility. Therefore, the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient.Rate this question:

The mean of four numbers a, b, c, d is 100. If c = 70 then the mean of the remaining numbers is
- A.
30
- B.
85/2
- C.
170/3
- D.
110
Correct Answer
D. 110Explanation
If the mean of four numbers a, b, c, d is 100 and c is 70, then the sum of the four numbers is 4 * 100 = 400. Since c is 70, the sum of the remaining three numbers is 400 - 70 = 330. To find the mean of the remaining numbers, we divide the sum by the number of remaining numbers, which is 3. Therefore, the mean of the remaining numbers is 330 / 3 = 110.Rate this question:

If the radius of a circle is increased by 50%, the perimeter of the circle will be increased by
- A.
20%
- B.
30%
- C.
40%
- D.
50%
Correct Answer
D. 50%Explanation
When the radius of a circle is increased by 50%, the new radius becomes 1.5 times the original radius. The perimeter of a circle is given by the formula P = 2πr, where r is the radius. Since the radius has increased by 50%, the new perimeter will be 2π(1.5r) = 3πr. This means that the new perimeter is 3 times the original perimeter. To find the percentage increase, we subtract 1 from 3 (3-1 = 2) and multiply by 100. Therefore, the perimeter of the circle will be increased by 200%, which is equivalent to a 100% increase.Rate this question:
