<p style="text-align: left;">1) All number of form 198k+194 leave the desired remanider as given for k>=0. So till k=4 u will get 3 digit numbers.therefore the ans is 5.</p>
<p style="text-align: center;">2)As the sum of 3 nonzero real numbers is 0.All the no. cant be negative or postive.</p>
Case 1: 1 number negative.(assume a) then abc is also negative. Thus u will get +2 for b and c and -2 for a and abc which equates to 0.

Case 2: 2 numbers negative.(assume a and b) . Then abc is postive. Thus u will get +2 for c and abc and -2 for a and b which equates to 0.

Thus the ans is 0.
