Explanation:

Correct option 3: 120

We are given a proportional analogy pattern in the form:

19 : 90 :: 25 : ? :: 13 : 60

Let’s look at the pattern between the number pairs:

First Pair: 19 : 90

Try squaring 19:

• 19²=361

But 361 is too far from 90. Let’s try a formula:

Try:

19×5−5=95−5=90  ---------->  It works.

Third Pair: 13 : 60

Check:

13×5−5=65−5=60 ------------> Works again.

So the pattern is:

Value=(Number)×5−5

Apply the same to the missing term:

Second Pair: 25 : ?

25×5−5=125−5= 120
