Question : If the LCM and the HCF of two numbers are 12 and 2 respectively, then find the mean proportional of these numbers.
Option 1: $2 \sqrt{6}$
Option 2: $\sqrt{14}$
Option 3: $2$
Option 4: $\sqrt{6}$
Correct Answer: $2 \sqrt{6}$
Solution : We know that LCM × HCF = Product of two numbers Now Mean proportion = $\sqrt{\text{Product of two numbers}}$ Given: LCM = 12 HCF = 2 $\therefore$ Product of two numbers $= 12 \times 2 = 24$ Mean proportion $=\sqrt{24} = \sqrt{4\times 6}=2\sqrt{6}$ Hence
