Step-by-step explanation:
Given : If 
and x and y are positive integers.
To find : Which of the following must be an integer?
Solution :
As we see all option there is a multiple of y.
So, we factoring the number 375
i.e. 
In order for 375y to be a perfect square,
The prime factorization of y must contain at least one 3 and one 5.
or y must be a multiple of 15.
If y is a multiple of 15, then 
must be an integer.
and 
must be an integer.
Therefore, I and III will be correct i.e. option d.
The number would be 7 because you divide 42/6 and get a result of 7.
