Which of the following is/are true?
Explanation:
If a number is divisible by a and b, it is also divisible by LCM(a, b).
Option (a): A number which is divisible by 12 and 3 is also divisible by LCM(12, 3) = 12. ∴ It cannot be definitely said that the number is divisible by 36.
Option (b): A number which is divisible by 4 and 9 is also divisible by LCM(4, 9) = 36. ∴ Option (b) is definitely true.
Option (c): A number which is divisible by 12 and 9 is also divisible by LCM(12, 9) = 36. ∴ Option (c) is definitely true.
Hence, option (d).
