GiveN:

• Two numbers 3 and 12

To FinD:

• Mean proportion to these two no.s.

Step-wise-Step Explanation:

Mean proportion is the number between two numbers let a and b which satisfies the equation a / x = x / b

Then,

• x = + √ab

Here, a = 3 and b = 12. By using the above Formula, let's find the mean proportion to these no.s

⇒ Mean proportion = +√3 * 12

⇒ Mean proportion = +√36

⇒ Mean proportion = +6

Hence the correct option is 6 ( B )
