Answer : 75

Explanation:

\(\text{ First number } \times \text{ Second number }= \text{ LCM } \times \text{ HCF}\)

\(\therefore \text{ Second number }= \frac{ \text{ LCM } \times \text{ HCF}}{ \text{ First number } }\)

Given, First Number = 60, HCF =15, LCM = 300

\(\therefore \text{ Second number }= \frac{ \text{ 300 } \times \text{ 15 }}{ \text{60 } }\)

\(\therefore \text{ Second number = 75}\)
