RRB ALP 2025 CBT 2 Mechanic Motor Vehicle Question Paper (28-Jul-2026) (Shift 1)
The correct answer is
22.22%

To solve this problem, we need to find out what percentage 4% of a number is with respect to 18% of the same number. Let's go through the solution step by step.

  1. Let the original number be denoted by \(x\).
  2. The problem states: \(\text{Percentage of } \frac{4\% \text{ of } x}{18\% \text{ of } x}\).
  3. First, calculate 4% of \(x\):

\(4\% \text{ of } x = \frac{4}{100} \times x = 0.04x\)

  1. Next, calculate 18% of \(x\):

\(18\% \text{ of } x = \frac{18}{100} \times x = 0.18x\)

  1. Now, we need to find the ratio of 4% of \(x\) to 18% of \(x\) and convert it to a percentage:

\(\text{Percentage} = \left(\frac{0.04x}{0.18x}\right) \times 100\%\)

  1. Simplify the ratio:

\(\frac{0.04x}{0.18x} = \frac{0.04}{0.18} = \frac{4}{18} = \frac{2}{9}\)

  1. Convert the simplified fraction to a percentage:

\(\frac{2}{9} \times 100\% = 22.22\%\)

Therefore, 4% of a number is approximately 22.22% of 18% of the same number. Hence, the correct answer is 22.22%.
