Determine the rounding digit and look to the right side of it.
If that digit is 4,3, 2 or 1 drop all digits to the right of it.
If that digit is 5, 6, 7, 8 or 9 add one to the rounding digit and drop all digits to the right of it.
Stmt I
.75n9 becomes .755 therefore n must have been 4 (inclusive)
Nearest percentage point being 75
SUFF
Stmt II
0<N<4 again makes n=1,2,3,4 and the nearest percentage point to 75
SUFF
D)
