90% of the population of a village is 25560. The total population of the village is:

Appeared in: DSSSB 13 August 2024

Explanation

  • The problem states that a part of the population (25,560) is equal to 90% of the total.
  • To find the total population (the 'whole'), we can use the formula: Whole = Part / Percentage.
  • In this case, the equation is: Total Population = 25,560 / 0.90.
  • Solving this equation gives the total population as 28,400.

Why Other Options Were Wrong

  • Option A: This is an incorrect calculation. 90% of 36,656 is 32,990.4, which is not the given population part of 25,560.
  • Option B: This is an incorrect calculation. 90% of 29,336 is 26,402.4. This value is relatively close to 25,560 but is not the correct answer.
  • Option C: This is an incorrect calculation. 90% of 30,040 is 27,036, not 25,560.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Solving for the whole amount given a part and its percentage as background academic context rather than a clinical decision trigger.
  • Basic math skills, including percentage calculations, are fundamental for safe and effective nursing practice.
  • Nurses frequently use percentages for medication dosage calculations, such as titrating IV drips or preparing solutions from stock concentrations.
  • Percentages are also used to assess patient progress, like calculating the percentage of weight loss in a pediatric patient or the percentage of body surface area affected by a burn.
How to Approach the Question
  • First, identify what is given: a part (25,560) and its corresponding percentage (90%).
  • Next, identify what needs to be found: the total population (the 'whole').
  • Set up an equation. Let 'P' be the total population. The equation is: 0.90 × P = 25,560.
  • Solve the equation for the unknown variable 'P' by dividing the part by the percentage (in decimal form): P = 25,560 / 0.90.
  • Calculate the result and match it with the given options.
