Find the mean proportional of 12.96 and 0.16.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1.44.
Let the mean proportion = x
So, 12.96/x = x/0.16
⇒ x2 = 12.96 × 0.16 = 2.0736
⇒ x = √2.0736 = 1.44
Therefore, the mean proportional of 12.96 and 0.16 is 1.44.
