Two numbers are in the ratio 5: 6. If their HCF is 5, then their LCM will be
Correct Answer: Option D
Two numbers are in the ratio 5: 6.
∴ If one number is 5X then other one is 6X.
The HCF of the above two numbers is X as 5 & 6 are relative prime numbers. So the highest common factor present between them = X
Given that, their HCF is 5
⇒ X = 5
∴The two numbers are 5×5 = 25; 6×5 = 30;
Now LCM of 25 & 30 is 150.
