Difficulty: Easy
Correct Answer: 2809
Explanation:
Introduction / Context:
This is a direct arithmetic evaluation using order of operations: division before addition. Such questions test speed and accuracy under basic BODMAS/PEMDAS rules.
Given Data / Assumptions:
Concept / Approach:
Evaluate 42060 / 15 first, then add 5 to the quotient. Keeping computations clean avoids transcription errors with larger numbers.
Step-by-Step Solution:
Divide: 42060 / 15 = 2804 (since 15 * 2804 = 42060).Add: 2804 + 5 = 2809.
Verification / Alternative check:
Break division: 42060 / 3 = 14020; 14020 / 5 = 2804. Then add 5 → 2809. Same result.
Why Other Options Are Wrong:
2804 omits the final addition; 2103, 289, and 2814 result from arithmetic slips or wrong operation order.
Common Pitfalls:
Adding before dividing; dividing incorrectly by 10 or 5; copying a partial result as final.
Final Answer:
2809
