The HCF of two numbers is 15 and their LCM is 300. If one of the number is 60, the other is:

The HCF of two numbers is 15 and their LCM is 300. If one of the number is 60, the other is:
[A]75
[B]65
[C]50
[D]100

75
Because, First number \times Second number = LCM \times HCF
∴ Second Number = \frac{15\times 300}{60}=75
Hence option [A] is the right answer.
