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 $\therefore \text{ Second number }= \frac{ \text{ 300 } \times \text{ 15 }}{ \text{60 } }$ $\therefore \text{ Second number = 75}$ Nithin K ? answered Dec 4 '2016 at 19:23 All Comments
