Detailed Solution & Explanation

**Step 1: Apply the range formula.** Range=Largest value−Smallest value\text{Range} = \text{Largest value} - \text{Smallest value} 20=Largest value−520 = \text{Largest value} - 5 Largest value=25\text{Largest value} = 25 Hence, **Option B** is the correct answer.

Exam Strategy Tip

Do not just memorize formulas; ICAI loves asking about the mathematical properties (e.g., 'sum of deviations from the AM is always zero'). You can usually eliminate 2 options just by knowing the properties.
