Question

Find the value of x if the following number are in proportion 135,105,x,7​

Answer 1

Dear Student,

◆ Answer -

x = 9

● Explaination -

Given that 4 numbers 135, 105, x and 7 are in proportion. i.e. 135:105 = x:7.

So now,

135/105 = x/7

Rearranging,

x = 135/105 × 7

x = 9/7 × 7

x = 9

Hence, value of x is 9.

Thanks dear for asking. Hope this is helpful to you...

Answer 2

The value of x is equal to 9.

Step-by-step explanation:

We have,

135 : 105 : : x : 7

To find, the value of x = ?

∴ 135 : 105 : : x : 7

Here, a = 135, b = 105, c = x and d =7

We know that,

Product of means = Product of extremes

⇒ b × c = a × d

∴  105 × x = 135 × 7  

⇒ x = $\dfrac{135 \times 7}{105}$

⇒ x = $\dfrac{135}{15}$

⇒ x = 9

Thus, the value of x is equal to 9.
