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
Now,
And,
Therefore,
0.9 : 36 = 10 : 4
Hence,
The given statement is true.
