Question

For what value of x will the following numbers be in proportion? 15, x , 27, 36 *




​

Answer 1

Answer:48

Step-by-step explanation:Continue proportional=a:b::b:c

A=27

B=36

C=x

so,

27:36::36:x

Now Multiply a×c=b×b

27×x=36×36

27x=1296

x=1296/27

x=48

Answer 2

Answer:

The value of x is 20.

Step-by-step explanation:

In this question,

It has been given that $15, x , 27, 36$ are in proportion.

We have to find the value of x.

We know that in a proportion:-

$\text { Product of extremes }=\text { Product of means. }$

Here,

Extremes = $15$ and $36$

Means = $x$ and $27$

Therefore,

=> $x\times 27= 15\times 36$

Multiplying the numbers on both sides,

=> $27x = 540$

Transposing $27$ from LHS to RHS:

$=> x = \frac{540}{27}$

Dividing $540$ by $27$,

=> $x = 20$

Hence, the required solution will be 20.
