Question

If 36:81: : x:63,find the value of x
​

Answer 1

Answer:

28

Step-by-step explanation:

36:81::X:63

36/81::x: 63

4/9::x:63

product of means = product of extremes

4x63=X x 9

4x63/9=X

4x7=X

X=28

Answer 2

Given:

The two ratios are in proportion.

To find:

We have to calculate the value of X.

Solution:

We know that when two ratios are in proportion,

Then both the ratios are equal to each other.

Since,

36:81 :: X:63

Therefore, 36/81 = X/63

We can solve this relation to get the value of x.

X = (36× 63) / 81

X= 2268 / 81

X= 28

The value of X is 28.
