Explanation opens after your attempt
Correct Answer

A. (2520)

Step 1

Concept

The (5) students receive one prize each from (7) prizes in an ordered way, so \(^{7}P_5=2520\). In exams, distinct recipients imply permutation.

Step 2

Why this answer is correct

The correct answer is A. (2520). The (5) students receive one prize each from (7) prizes in an ordered way, so \(^{7}P_5=2520\). In exams, distinct recipients imply permutation.

Step 3

Exam Tip

(5) विद्यार्थियों को (7) पुरस्कारों में से क्रमित रूप से एक-एक मिलेगा, इसलिए \(^{7}P_5=2520\)। परीक्षा में recipients अलग हों तो permutation लें।
