अंकों (0,1,2,3,4) से बिना पुनरावृत्ति (3) अंकों की कितनी संख्याएं बनेंगी?
How many (3)-digit numbers can be formed from (0,1,2,3,4) without repetition?
Explanation opens after your attempt
A. (48)
Concept
The hundreds place cannot be (0), so \(4\cdot4\cdot3=48\). In exams, always check the zero restriction on the first digit.
Why this answer is correct
The correct answer is A. (48). The hundreds place cannot be (0), so \(4\cdot4\cdot3=48\). In exams, always check the zero restriction on the first digit.
Exam Tip
सैकड़े के स्थान पर (0) नहीं आ सकता, इसलिए \(4\cdot4\cdot3=48\)। परीक्षा में प्रथम अंक पर शून्य की शर्त जरूर जांचें।
