Question

Find x , where x:3::4:12.​

Answer 1

Answer:

If x:3::4:12 then x = 1.

Step-by-step explanation:

If a: b::c:d, then a/b = c/d

If x:3::4:12 then find x

$\frac{x}{3} =\frac{4}{12}$

By cross multiplication

12 × x = 4 × 3

12x = 12

Divide both side by 12

12x÷ 12 = 12÷ 12

x= 1

So, If x:3::4:12 then x = 1.

Answer 2

Given :-

x : 3 :: 4 : 12

To Find :-

Value of x

Solution :-

We know that

Product of means = Product of extremes

⇒ x × 12 = 4 × 3

⇒ 12x = 12

⇒ x = 12/12

⇒ x = 1

Hence,

Value of x is 1
