Plz give answer with solution​

Answer 1

Given data:

x : 12 :: 5 : 6

To find:

The value of x

Step-by-step explanation:

Given, x : 12 :: 5 : 6

We apply the formula,

product of the first term and the fourth term = product of the second term and the third term

• or, product of the extremes = product of the means

⇒ x * 6 = 12 * 5

⇒ x * 6 = 60

⇒ x = 60/6

⇒ x = 10

Answer:

Therefore the value of x is 10

Checking step

When x = 10,

• first ratio = 10 : 12 = 5 : 6
• second ratio = 5 : 6

So, first ratio = second ratio

Thus the value of x (= 10) is satisfactory.
