Question : Two numbers are in the ratio of 4 : 3. The product of their HCF and LCM is 2700. The difference between the numbers is:
Option 1: 15
Option 2: 30
Option 3: 25
Option 4: 105
Correct Answer: 15
Solution : Ratio of Two numbers = 4 : 3 HCF × LCM = 2700 Product of two numbers = Product of their HCF and LCM Let the numbers be $4x$ and $3x$ respectively ⇒ $x × 12x = 2700$ ⇒ $12x^2 = 2700$ ⇒ $x^2 = 225$ ⇒ $x = 15$ Difference between the numbers is $=4x - 3x = x = 15$ Hence, the correct answer is 15.
