Answer 1

সঠিক উত্তর হচ্ছে: 10080

ব্যাখ্যা:

• ♦We know that, the least number of 5 digits is 10000. 
• ♦L.C. M. of 12, 15 and 18 is = 180. 
• ♦So, the required number must be divisible by 180.
•  
• ♦On dividing 10000 by 180, the reminder is 100. 
•  
• ♣Therefore, the required number is = {10000 + (180 – 100)} = 10080.
