Question

5. If 27 : 72 :: X:8, find the value of x.​

Answer 1

Step-by-step explanation:

Given:-

27 : 72 :: X:8

To find:-

If 27 : 72 :: X:8, find the value of x.

Solution:-

Given proportion is 27:72::X:8

We have , Means = 72 and X

Product of means = 72×X = 72X

Extremes = 27 and 8

Product of extremes = 27 × 8 = 216

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

=>72X = 216

=>X = 216/72

=>X = 3×72/72

=>X = 3

Therefore, X = 3

Answer:-

The value of X for the given problem is 3

Check:-

27:72::3:8

Product of extremes= 27×8=216

Product of means=72×3=216

Used formula:-

In proportion The product of extremes is equal to the product of means
