Answer :

In the given question,

We have to check if the given statement is true.

To check it we will show if the ratio of terms are equal or not.

(a)16 : 24 : : 20 : 30

Now,  

And, 

Therefore,

16 : 24 : : 20 : 30

Hence,

The given statement is true.

(b) 21 : 6 : : 35 : 10

Now, 

And, 

Therefore, 21 : 6 : : 35 : 10

The given statement is true.

(c) 12 : 18 : : 28 : 12

Now, 

And, 

Here, 12 : 18 ≠ 28 : 12

Hence, the given statement is false.

(d) 8 : 9 : : 24 : 27

Now, 

And, 

Therefore,

8 : 9 = 24 : 27

The given statement is true.

(e)  5.2 : 3.9 : : 3 : 4

Now, 

And, 

Here,

5.2 : 3.9 ≠3 : 4

Hence,

The given statement is false.

(f) 0.9 : 0.36 : : 10 : 4
