What is the ratio of the expenses on Clothing to the expenses on Rent?

Appeared in: DSSSB October 2024

Explanation

  • The question requires finding the ratio of expenses on Clothing to the expenses on Rent.
  • By observing the pie chart, the percentage of spending on Clothing is clearly marked as 12%.
  • Similarly, the percentage of spending on Rent is marked as 25%.
  • A ratio is a comparison of two numbers. To find the ratio of Clothing to Rent, we write the percentage for Clothing first, followed by the percentage for Rent.
  • This results in the ratio 12:25, which cannot be simplified further.

Why Other Options Were Wrong

  • Option B: This ratio is incorrect because the percentage for Clothing is 12%, not 23%. The value '23' does not appear anywhere in the pie chart data.
  • Option C: This option incorrectly reverses the order of the ratio. It represents the ratio of Rent to Clothing (25:12), not Clothing to Rent. It also uses an incorrect value of 23.
  • Option D: This ratio is incorrect because the percentage for Rent is 25%, not 23%. The value '23' is not associated with any category in the chart.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Interpreting data from a pie chart and calculating ratios as background academic context rather than a clinical decision trigger.
  • While not a clinical question, data interpretation is a critical skill for nurses to accurately read patient charts, lab value reports, and graphical data from monitoring equipment.
  • Understanding ratios is fundamental for safe medication administration, especially in drug calculations, preparing solutions, and setting infusion rates.
  • For example, a nurse might need to mix a medication in a 1:100 ratio, meaning 1 part medication to 100 parts diluent.
How to Approach the Question
  • Step 1: Carefully read the question to identify the two quantities to be compared and their required order. Here, it is 'Clothing to Rent'.
  • Step 2: Locate these two categories ('Clothing' and 'Rent') on the provided pie chart.
  • Step 3: Read the percentage value corresponding to the first category, Clothing, which is 12%.
  • Step 4: Read the percentage value corresponding to the second category, Rent, which is 25%.
  • Step 5: Write the two values as a ratio in the specified order: 12:25.
  • Step 6: Check if the ratio can be simplified by finding a common divisor. In this case, 12 and 25 have no common divisors other than 1, so the ratio is already in its simplest form.
