How many (5)-digit numbers divisible by (25) can be formed from digits (0,1,2,3,4,5,6,7,8,9) without repetition?अंकों (0,1,2,3,4,5,6,7,8,9) से बिना पुनरावृत्ति कितनी (5)-अंकीय संख्याएं (25) से विभाज्य होंगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (924)(924)
The last two digits can be (25,50,75), and leading-zero cases must be removed separately. For divisibility by (25), check the last two digits first.अंतिम दो अंक (25,50,75) हो सकते हैं और अग्र शून्य की स्थिति अलग हटानी होगी। (25) से विभाज्यता में अंतिम दो अंक पहले जांचें।
