Answer 2

The value of  mean proportion of 25 : 10 : : 10 : 4 = 10

Step-by-step explanation:

We have,

25 : 10 :: 10 : 4

To find, the value of  mean proportion of 25 : 10 : : 10 : 4 = ?

We know that,

a : b : : c : d  are in mean proportion.

∴ $b^{2} =ac$

Here, a = 25, b = 10 and c = 4

∴ $10^2$ = 25 × 4 = 100

⇒ 100 = 100

∴ The value of  mean proportion of 25 : 10 : : 10 : 4 = 10
