Of course, you know the answer after figuring the third line of the table.
The two numbers are 27 and 58.
_____
If the second number is odd, the result after subtracting 4 will not be divisible by 2. This lets you reject the 1st and 4th choices immediately. As for the second choice, twice 25 is 10 less than 60, not 4 less, so that choice can also be discarded.
Starting from the system of equations
you can use substitution to get
This identifies the 3rd selection as the appropriate one.
