Options can be re-written as (x-5)x => 1-(5/x)

A) 1- (5/3257)
B) 1- (5/3461)
C) 1- (5/3596)
D) 1- (5/3351)
E) 1- (5/3458)

To get the largest among these second half should be the least and so denominator to be largest. Hence 'C'.

The rule we can use here is that => " Whenever we add the same constant to both the numerator and the denominator of a positive fraction, the fraction approaches one"


Now As for this Question
Let 3252/3257 be the original fraction.
Notice that it is a positive Proper fraction.
Hence adding the same constant to both the numerator and the denominator will increase the fraction as the fraction will move closer to one.
Hence we just have to pick the number that adds the greatest value to both the numerator and the denominator.
So It must be C.

Like this method. Kudos !!

Also, we can see the difference between Numerator and denominator is same for all options. So, bigger the value of numerator and denominator, bigger the fraction.
One more point to add here - in this question, all fractions are proper fractions (Num is smaller than den), but when num is bigger than den (improper fractions) and difference is same for 2 fractions (5/4 and 7/6), in such case the bigger the numerator, smaller the value of fraction.

Hope this helps.
