Answer
Correct Answer: 11
Explanation
### Concept & Logic
When asked for the least number to subtract from a given value to make it exactly divisible, the answer is simply the remainder obtained when dividing the given value by the divisor.
### Step-by-Step Solution
- **Given:** Dividend = 2000, Divisor = 17.
- **Calculation / Deduction:** Perform standard division of 2000 by 17.
- $2000 = 17 \times 117 + 11$.
- The division yields a remainder of 11.
- This remainder is the exact extra amount that prevents 2000 from being a perfect multiple. Removing it gives a perfectly divisible number.
### Exam Strategy & Shortcut
For subtraction-based divisibility questions, your calculation stops the moment you find the remainder. The remainder itself is your final answer. Do no further arithmetic.
### Common Pitfall
Students sometimes confuse the rules for adding and subtracting. Subtracting the remainder from the divisor ($17 - 11 = 6$) is the rule for finding what to *add*. For subtraction, just use the direct remainder.
### Final Answer
Therefore, the correct answer is 11.
