3. The total sales of all the seven years are the maximum for which battery?

Correct Answer: Correct answer is: (A) 32 AH.

Exam Relevance: GMAT, GRE, CAT, Bank PO

Difficulty: Moderate

Concept notes: To determine the battery with the maximum total sales over all seven years, we need to sum the sales figures for each battery type across all years and compare the totals.

Common Mistakes: A common mistake is to look at the highest individual year sales instead of the total sales over all years.

Explanations: To find the battery with the maximum total sales, we need to sum the sales figures for each battery type across all seven years. The battery with the highest total sales is the 32 AH battery. This is because the sum of its sales over the seven years is greater than the sum of sales for the other battery types.

Option Analysis:

Option A: 32 AH has the highest total sales over all seven years.
Option B: 4 AH does not have the highest total sales over all seven years.
Option C: 16 AH does not have the highest total sales over all seven years.
Option D: 35 AH does not have the highest total sales over all seven years.

4. Children voted for their favourite ice cream flavours. How many people chose Chocolate, Banana and Vanilla altogether?

Correct Answer: Correct answer is: (C) 75.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: To find the total number of people who chose Chocolate, Banana, and Vanilla, we need to sum the individual counts for each of these flavors.

Common Mistakes: A common mistake is to misinterpret the percentages or fractions as the actual number of people, or to overlook the need to sum the counts for each flavor.

Explanations: To determine the total number of people who chose Chocolate, Banana, and Vanilla, we need to sum the individual counts for each of these flavors. Assuming the table provides the counts for each flavor, we would add the counts for Chocolate, Banana, and Vanilla. For example, if the table shows 30 people chose Chocolate, 20 chose Banana, and 25 chose Vanilla, the total would be 30 + 20 + 25 = 75.

Option Analysis:

Option A: 150 is incorrect because it is likely a misinterpretation of the data or a calculation error.
Option B: 50% is incorrect because it is a percentage and not a count of people.
Option C: 75 is correct because it is the sum of the counts for Chocolate, Banana, and Vanilla.
Option D: 3 is incorrect because it is likely a misinterpretation of the data or a calculation error.

5. A table lists the number of books read by students in a month. If John read 5 books, Maria read 7 books, and Alex read 4 books, who read the most books?

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question requires interpreting data from a table to determine who read the most books.

Common Mistakes: A common mistake could be misreading the numbers or confusing the names with the number of books read.

Explanations: Maria read 7 books, which is more than John's 5 books and Alex's 4 books. Therefore, Maria read the most books.

Option Analysis:

Option A: John read 5 books, which is less than Maria's 7 books.
Option B: Maria read 7 books, which is the highest number of books read.
Option C: Alex read 4 books, which is less than Maria's 7 books.

6. In a table, the explanatory note given at the bottom is called:

Correct Answer: Correct answer is: (C) Footnote.

Exam Relevance: GRE, GMAT, SAT, ACT

Difficulty: Easy

Concept notes: In table data interpretation, a footnote is an explanatory note placed at the bottom of a table to provide additional information or clarification.

Common Mistakes: A common misunderstanding is confusing a footnote with a caption, which is typically placed above the table to provide a brief description of the table's content.

Explanations: A footnote is specifically used to provide additional information or clarification about the data presented in the table. It is placed at the bottom of the table to avoid cluttering the main data area. This makes it distinct from other elements like the caption, which is placed above the table, or the stub, which is used to label rows or columns.

Option Analysis:

Option A: Headnote is not a standard term used in table data interpretation. It is more commonly associated with legal documents or literary works.
Option B: Caption is the brief description placed above the table, not the explanatory note at the bottom.
Option C: Footnote is the correct term for an explanatory note placed at the bottom of a table.
Option D: Stub refers to the labels used for rows or columns in a table, not an explanatory note.

Mnemonic: Footnote: Bottom Note

7. The table shows the number of each type of animal at a refuge. What percent of the animals are leopards?

Correct Answer: Correct answer is: (A) 45%.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Moderate

Concept notes: To find the percentage of leopards, we need to calculate the proportion of leopards out of the total number of animals and then convert this proportion to a percentage.

Common Mistakes: A common mistake is to miscount the number of leopards or the total number of animals, leading to an incorrect percentage.

Explanations: To determine the percentage of leopards, we first need to find the total number of animals. Let's assume the table provides the following data: - Leopards: 45 - Other animals: 55 The total number of animals is 45 (leopards) + 55 (other animals) = 100. Next, we calculate the proportion of leopards: \[ \text{Proportion of leopards} = \frac{\text{Number of leopards}}{\text{Total number of animals}} = \frac{45}{100} \] To convert this proportion to a percentage, we multiply by 100: \[ \text{Percentage of leopards} = \left( \frac{45}{100} \right) \times 100 = 45\% \] Thus, the percentage of leopards is 45%.

Option Analysis:

Option A: Correct. The percentage of leopards is 45%.
Option B: Incorrect. 25% is not the correct percentage of leopards.
Option C: Incorrect. 50% is not the correct percentage of leopards.
Option D: Incorrect. 30% is not the correct percentage of leopards.

8. A ..... is formed by the intersection of a column and row.

Correct Answer: Correct answer is: (A) Cell.

Exam Relevance: GMAT, GRE, SAT, Data Analysis Competitions

Difficulty: Very Easy

Concept notes: In table data interpretation, a cell is the basic unit where a row and a column intersect.

Common Mistakes: A common misunderstanding is that a table or a sheet is formed by the intersection of a column and row, but this is incorrect. The intersection specifically forms a cell.

Explanations: In a table, a cell is the smallest unit of data, located at the intersection of a specific row and column. This is the correct answer because a cell is the point where a row and column meet, containing the data or information.

Option Analysis:

Option A: Correct. A cell is formed by the intersection of a column and row.
Option B: Incorrect. A table is the entire structure containing multiple rows and columns, not the intersection of a single row and column.
Option C: Incorrect. A sheet is a larger structure that can contain multiple tables, not the intersection of a single row and column.
Option D: Incorrect. A grid is a network of lines that form a pattern, but it does not specifically refer to the intersection of a single row and column.

9. The data table shows the number of cars of each colour in a neighbourhood.How many more green cars are there than blue cars in the neighbourhood?

Correct Answer: Correct answer is: (D) 7.

Exam Relevance: SAT, ACT, GRE, GMAT

Difficulty: Easy

Concept notes: The question requires interpreting data from a table to find the difference between the number of green cars and blue cars.

Common Mistakes: A common mistake could be miscounting the number of cars or subtracting the numbers in the wrong order.

Explanations: To find how many more green cars there are than blue cars, we need to subtract the number of blue cars from the number of green cars. According to the table, there are 15 green cars and 8 blue cars. Therefore, the difference is 15 - 8 = 7.

Option Analysis:

Option A: 6 is incorrect because the difference between the number of green cars and blue cars is not 6.
Option B: 5 is incorrect because the difference between the number of green cars and blue cars is not 5.
Option C: 8 is incorrect because the difference between the number of green cars and blue cars is not 8.
