D. 25​

Answer 1

Option - B

Step-by-step explanation:

Given:-

3,5 ,X and 15 are in Proportion

To find:-

Find the value of x if 3,5 ,X and 15 are in Proportion ?

Solution:-

Given that

3,5,X and 15 are in the Proportion

Extremes = 3 and 15

Product of extremes

= 3×15

= 45

Means = 5 and X

Product of means

= 5×X

= 5X

We know that

In proportion, The product of means = The product of extremes

=>5X = 45

=> X = 45/5

=> X = 9

Therefore, X = 9

Answer:-

The value of X for the given problem is 9

Used formula:-

In proportion,

• The product of means = The product of extremes
