Question

Find the value of x in the following proportion 14:30:: 7:x​

Answer 1

Step-by-step explanation:

Given:-

14:30:: 7:x

To find:-

Find the value of x in the following proportion

Solution:-

Given Proportion is 14:30:: 7:x

Extremes in the given proportion = 14 and x

Means in the given proportion = 30 and 7

Product of extremes = 14x

Product of means = 30×7 = 210

We know that

In the Proportion,

Product of extremes = Product of means

=>14x = 210

=>x = 210/14

=>x = 15

The value of x = 15

Answer:-

The value of x in the given Proportion is 15

Check:-

Given Proportion becomes 14:30::7:15

Product of extremes = 14×15 =210

Product of means = 30×7 = 210

Product of extremes = Product of means

Verified the given relation.

Used formula:-

• Equality of ratios is called proportion.

• In proportion Product of means is equal to Product of extremes.

• If a,b,c,d are in the Proportion then bc = ad
