The ratio between the fourth proportional of 2, 8 and 12 to the mean proportional of 9 and 4 is:

Correct option is C

Given:
The first three numbers are 2, 8, and 12.
The two numbers for the mean proportional are 9 and 4.
Formula Used:
Fourth Proportional of a, b and c= $$\frac{b \times c} a$$​​
Mean Proportional of m and n = $$\sqrt{m n}$$​​
Solution:
Fourth Proportional $$= \frac{8 \times 12}{2} = \frac{96}{2} = 48$$​​
Mean Proportional =$$\sqrt{9 \times 4} = \sqrt{36} = 6$$​​
Ratio = $$\frac{48}{6} = \frac{8}{1}$$​​
