The question states

*n = Number of even factors of n other than n

Let's look at the definition of the given function here with a simple example:

For example to find *4, we need to find the number of even factors of 4 other than 4 itself.

What is the number of even factors of 4 ?

4 has following factors: 1,2 and 4

2 is the only even factor of 4 apart from 4 itself. That is "

number of even factors" of 4 apart from 4 itself is 1

So *4 = 1

Now coming to the question:

Qty A = *48

Factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Number of even factors other than 48 =

7 (2,4,6,8,12,16,24)

Qty A = *122

Factors of 122 are: 1, 2, 61, 122

Number of even factors other than 122 =

1 (2)

Qty A is 7 and Qty B is 1

Correct Answer:

Option A
