Question

let us find the value of x for the following proportion 10:35::x:42​

Answer 1

Step-by-step explanation:

Given :-

10:35::x:42

To find :-

find the value of x?

Solution:-

Given that

10:35::x:42

Extremes = 10 and 42

Product of extremes = 10×42 = 420

Means = 35 and X

Product of means = 35×X= 35X

We know that

In proportion,

Product of means=Product of extremes

35X = 420

=>X = 420/35

=>X = (12×35)/35

=>X = 12

Therefore,X = 12

Answer:-

The value of X for the given problem is 12

Used formula:-

• In proportion, Product of means=Product of extremes
