If 35 is the mean proportion of 25 and x, then what is the value of x?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 49.

The mean proportion between two numbers a and b is the square root of their product, i.e.,

Mean Proportion = √ab

Here, a = 25, and mean proportion = 35

Let b = x

So,

⇒ 35 = √25x

⇒ 352 = 25x

⇒ x = 1225/25

⇒ x = 49

So, b = 49
