💡 Analysis & Explanation

Concept of Mean Proportional ▼

The mean proportional 'x' between two numbers 'a' and 'b' is calculated using the geometric mean formula: x = √(a × b).

Calculation Steps ▼

Here, the given values are a = 0.06 and b = 6. Substituting these into the formula, we get x = √(0.06 × 6).

Final Evaluation ▼

Multiplying the values gives x = √(0.36). The square root of 0.36 is 0.6.

Conclusion ▼

The correct mean proportional is 0.6.
