Question

18 : 12 :: 6 : x pls sol it

Answer 1

Step-by-step explanation:

To find (x)

x:18::12:6 as 1×4=2×3

To proportionality

so 6x = 18 × 12

x=18×12/6

x=36

Answer 2

$\underline{ \underline{ \bf Question}}$

18 : 12 :: 6 : x

$\large\tt Answer$

$\bf x = 4$

Solution

We have to calculate the fourth term which bears the same ratio with 6 just like the ratio bears by 12 with 18 .

In more simpler words , we have to calculate that value for x such that the ratio of 6 : x must be equal or proportional to 18 : 12.

$\rm18 : 12 = 6 : x$

It can be written as :

$\bf \frac{18}{12} = \frac{6}{x}$

Now , perform cross multiplication ;

$: \implies \rm 18x = 6 \times 12 \\ \bf 18x = 72$

$\rm \: x = \cancel \frac{72}{18} \\ = 4$

Verification

Now , Let's check whether the value is correct

$18 : 12 = \cancel \dfrac{18}{12} = 3 : 2 \longrightarrow(1)$

Similarly,

$6 : 4 = \cancel \dfrac{6}{4} = 3: 2 \longrightarrow(2)$

Hence, verified also that the value for x = 4
