Clock strikes once at 1:00, twice at 2:00 & so on. If it takes 6 sec to strikes at 5:00 & 12 sec to strike at 9:00 & also time to strike at 1:00 is negligible than find time spent to strike for 24 hours.

From the quesition itself its clear that per interval (time between 2 strikes) it takes 1.5 seconds...
And clearly stated that at 1pm or 1am no need to calculate the time..
so consider the following table...
Time Interval Seconds taken for the interval
1AM 0 0
2AM 1 1.5
3AM 2 3.0
4AM 3 4.5
5AM 4 6
6AM 5 7.5
7AM 6 9
8AM 7 10.5
9AM 8 12.0
10AM 9 13.5
11AM 10 15
12AM 11 16.5
Calculate the third column 0+1.5+3+4.5+6+7.5+9+10.5+12.0+13.5+15.0+16.5 = 99??
then calculate for the other 12 hours.. so 99 + 99 == it must be 198
