2. What was the total amount of candy sold during the school year shown in the graph?

Correct Answer: Correct answer is: (D) 27.5.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: To find the total amount of candy sold during the school year, we need to sum the values of candy sold each month as shown in the graph.

Common Mistakes: A common mistake is to misread the values on the graph or to overlook some months, leading to an incorrect total.

Explanations: To determine the total amount of candy sold during the school year, we need to sum the values of candy sold each month as indicated on the graph. By carefully reading the graph, we can identify the monthly sales and add them together. The sum of these values is 27.5, which corresponds to the correct answer.

Option Analysis:

Option A: 43 is incorrect because it is a higher value than the sum of the monthly sales shown on the graph.
Option B: 35.5 is incorrect because it is also a higher value than the sum of the monthly sales shown on the graph.
Option C: 23 is incorrect because it is a lower value than the sum of the monthly sales shown on the graph.
Option D: 27.5 is the correct answer as it matches the sum of the monthly sales shown on the graph.

3. The chart above shows the number of pies sold by Jack, Tom, Stefan and Amir. If there are 800 pies altogether, how many pies did Jack sell?

Correct Answer: Correct answer is: (A) 200 pies.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question requires interpreting the data from a chart to determine the number of pies sold by Jack out of a total of 800 pies.

Common Mistakes: A common mistake could be misreading the chart or incorrectly calculating the proportion of pies sold by Jack.

Explanations: To find the number of pies sold by Jack, we need to determine the proportion of the total pies that Jack sold. If the chart indicates that Jack sold 25% of the total pies, then we can calculate the number of pies sold by Jack as follows: 1. Total number of pies = 800 2. Proportion of pies sold by Jack = 25% 3. Number of pies sold by Jack = 25% of 800 4. Number of pies sold by Jack = 0.25 * 800 = 200 pies

Option Analysis:

Option A: 200 pies. This is the correct answer as it matches the calculation based on the chart data.
Option B: 320 pies. This is incorrect as it does not match the proportion indicated in the chart.
Option C: 400 pies. This is incorrect as it does not match the proportion indicated in the chart.
Option D: 450 pies. This is incorrect as it does not match the proportion indicated in the chart.

4. Which statement best explains how literacy rates affect the standard of living?

Correct Answer: Correct answer is: (A) Higher literacy rates usually lead to a higher standard of living.

Exam Relevance: AP Human Geography, GRE, GMAT

Difficulty: Moderate

Concept notes: Higher literacy rates are often associated with better economic outcomes, improved health, and increased civic engagement, all of which contribute to a higher standard of living.

Common Mistakes: A common misunderstanding is that literacy rates do not significantly impact a country's development, which is incorrect.

Explanations: Higher literacy rates enable individuals to access more information, improve their skills, and participate more effectively in the workforce. This leads to better job opportunities, higher productivity, and economic growth, which in turn raises the standard of living.

Option Analysis:

Option A: This is the correct answer as higher literacy rates are linked to better economic and social outcomes.
Option B: This is incorrect because literacy rates do have a significant impact on a country's development.
Option C: This is incorrect because a lower literacy rate does not imply that people are more qualified for jobs; in fact, it often means the opposite.
Option D: This is incorrect because literacy rates are important for all types of economies, not just command economies.

5. You want to set such that when you type Baishakh and drag the fill handle, Excel should produce Jestha, Aashadh and so on. What will you set to effect that?

Correct Answer: Correct answer is: (A) Custom List.

Exam Relevance: Microsoft Excel Certification, Data Analyst Exams, Spreadsheet Competency Tests

Difficulty: Moderate

Concept notes: Custom List in Excel allows users to define a sequence of items that can be used for auto-filling. This is particularly useful for non-numeric sequences like months in different languages or custom sequences.

Common Mistakes: A common mistake is to assume that Excel's default auto-fill options can handle custom sequences like Nepali months. However, these options are limited to numeric sequences or predefined lists like days of the week or months of the year.

Explanations: To achieve the desired sequence of Nepali months (Baishakh, Jestha, Aashadh, etc.), you need to set up a Custom List in Excel. This allows you to define the specific order of the months, which Excel will then use when you drag the fill handle. The other options (Auto Fill Options, Fill Across Worksheet, Fill Series) do not provide the flexibility to define custom sequences.

Option Analysis:

Option A: Custom List is the correct choice as it allows defining a custom sequence of items for auto-filling.
Option B: Auto Fill Options are limited to predefined sequences and do not support custom sequences.
Option C: Fill Across Worksheet is used for filling data across multiple worksheets, not for custom sequences.
Option D: Fill Series is used for numeric sequences or predefined lists, not for custom sequences like Nepali months.

6. How many more mobile phones were sold in 2014 than in 2010?

Correct Answer: Correct answer is: (D) Four million.

Exam Relevance: GMAT, GRE, SAT, ACT

Difficulty: Moderate

Concept notes: The question requires interpreting data from a chart or table to determine the difference in the number of mobile phones sold between two years.

Common Mistakes: A common mistake would be misreading the data or incorrectly calculating the difference between the two years.

Explanations: To find the difference in the number of mobile phones sold between 2014 and 2010, we need to subtract the number of mobile phones sold in 2010 from the number sold in 2014. According to the data, the number of mobile phones sold in 2014 is 12 million, and in 2010, it is 8 million. Therefore, the difference is: 12 million - 8 million = 4 million.

Option Analysis:

Option A: One million is incorrect because the difference is larger.
Option B: Two million is incorrect because the difference is larger.
Option C: Three million is incorrect because the difference is larger.
Option D: Four million is correct as it matches the calculated difference.

7. How do you determine the number of students with all three streaming services using a Venn diagram?

Correct Answer: Correct answer is: (C) Look for the intersection of all three sets in the Venn diagram.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: In a Venn diagram, the intersection of all three sets represents the students who have all three streaming services.

Common Mistakes: A common mistake is to confuse the intersection with the union of the sets, which would include all students with at least one streaming service.

Explanations: The intersection of all three sets in a Venn diagram represents the students who are part of all three sets simultaneously. This means these students have all three streaming services. Therefore, to find the number of students with all three streaming services, you need to look at the intersection of all three sets.

Option Analysis:

Option A: The union of all three sets would include all students with at least one streaming service, not those with all three.
Option B: Counting the total number of students in the diagram would include all students, not just those with all three streaming services.
Option C: The intersection of all three sets correctly identifies the students with all three streaming services.
Option D: Adding the number of students in each individual set would overcount students who belong to multiple sets.

Mnemonic: Intersection = All Three

8. Share Price of Company X at the beginning of year is Rs.100 & at the end of year is Rs.120. Dividend per share is Rs.6. What should be the return from this security?

Correct Answer: Correct answer is: (A) 26%.

Exam Relevance: CFA, CA Final, MBA Finance, GRE Quantitative

Difficulty: Moderate

Concept notes: The return from a security can be calculated by considering both the capital gain and the dividend yield.

Common Mistakes: A common mistake is to only consider the capital gain or the dividend yield separately, rather than combining both to get the total return.

Explanations: To calculate the return from the security, we need to consider both the capital gain and the dividend yield. 1. Calculate the capital gain: - Initial share price: Rs. 100 - Final share price: Rs. 120 - Capital gain = Final share price - Initial share price = Rs. 120 - Rs. 100 = Rs. 20 2. Calculate the dividend yield: - Dividend per share: Rs. 6 3. Calculate the total return: - Total return = (Capital gain + Dividend) / Initial share price - Total return = (Rs. 20 + Rs. 6) / Rs. 100 = Rs. 26 / Rs. 100 = 0.26 or 26% Thus, the return from this security is 26%.

Option Analysis:

Option A: Correct. The total return is 26%.
Option B: Incorrect. This option only considers the capital gain (20%) and ignores the dividend yield (6%).
Option C: Incorrect. This option only considers the dividend yield (6%) and ignores the capital gain (20%).
Option D: Incorrect. This option does not correctly combine the capital gain and dividend yield.

9. Which sentence is most likely from an argumentative text?

Correct Answer: Correct answer is: (B) The data clearly shows a 20% increase in sales.

Exam Relevance: GRE, GMAT, LSAT, SAT

Difficulty: Easy

Concept notes: Argumentative texts often use data and statistics to support claims and arguments.

Common Mistakes: A common mistake is to confuse narrative or descriptive sentences with argumentative ones.

Explanations: The sentence "The data clearly shows a 20% increase in sales" is most likely from an argumentative text because it presents a factual claim supported by data, which is a common feature in argumentative writing.

Option Analysis:

Option A: This is a narrative opening, not argumentative.
Option B: This presents a factual claim supported by data, typical in argumentative texts.
Option C: This is a descriptive sentence, not argumentative.
Option D: This is an emotional or subjective statement, not argumentative.

10. Which form of correlation does the given data set have? Increase in time spent playing sports, decrease in grade point average.

Correct Answer: Correct answer is: (D) Negative Correlation.

Exam Relevance: AP Statistics, GRE, GMAT, SAT

Difficulty: Moderate

Concept notes: Correlation measures the relationship between two variables. A negative correlation indicates that as one variable increases, the other variable decreases.

Common Mistakes: A common mistake is confusing positive correlation with negative correlation. Positive correlation means both variables increase together, while negative correlation means one variable increases as the other decreases.

Explanations: In the given data set, as the time spent playing sports increases, the grade point average decreases. This indicates a negative relationship between the two variables, hence the correct answer is negative correlation.

Option Analysis:

Option A: Positive Correlation is incorrect because it would imply that both variables increase together, which is not the case here.
Option B: No Correlation is incorrect because there is a clear relationship between the variables, even though it is negative.
Option C: Discriminating Correlation is not a standard term in data interpretation and is incorrect.
Option D: Negative Correlation is correct because it accurately describes the inverse relationship between the variables.
