(1) Hundred's place digit of N is three times its unit's place digit, and is half of its ten's place digit.
N =100a+10b+c
also,
a=3c and
b=2a
the smallest possible value of c =1
so N = 361
sufficient.
(2) [N/10] = 36, where [x] represents the greatest integer less than or equal to x.
again N >= 360
sufficient
