Answer 2

Answer:

The value of x is 12.5.

Given : If 2, 5, x are in proportion.

To find : The value of 'x' ?

Solution :

If 2, 5, x are in proportion i.e. 2:5:5:x

 Product of extremes = Product of means

i.e. b² = ac

Here, a = 2, b = 5 and c = x

Substitute,

5² = 2x

25 = 2x

x = 25/2

x = 12.5

Therefore, the value of x is 12.5
