Stmt I
n = 110q+75
110 always divisble by 10 so the remiander will be what 75 will leave when divided by 10 i.e 5
SUFF
Stmt II
n = 100q+25
100 always divisble by 10 so the remiander will be what 25 will leave when divided by 10 i.e 5
SUFF
Only prob is the 2 statements here contradict each other i.e. if we take n=75 then it does not leave a remainder 25 when divided by 100. In gmat q's this will not be the case

Yes, n can't be 75, but the statements aren't contradictory - n could be 625, 1725, 2825, etc.cramya wrote: Only prob is the 2 statements here contradict each other i.e. if we take n=75 then it does not leave a remainder 25 when divided by 100. In gmat q's this will not be the case

Basically,
the question is asking ...what is the unit digit of n
Using both statements independently,
each time unit digit is 5 (use VIC method)
hence D.
