Download Solution PDFGiven:
Let a be a positive number and b = 4/a.
Formula used:
The mean proportional of a and b is given by the square root of their product, i.e., √(a × b).
Calculations:
a = a
b = 4/a
Mean proportional = √(a × b)
⇒ Mean proportional = √(a × 4/a)
⇒ Mean proportional = √4
⇒ Mean proportional = 2
∴ The correct answer is option (3).
