198 seconds
to cover up 4 intervals=6seconds
1 gap=1.5 sec
2*(1.5+3.0+4.5+6+7.5+9+10.5+12+13.5+15+16.5+0)=198 seconds
as first interval takes 0 second 5-1 take 6 seconds
6/4= 1.5

A Clock strikes every hour-once at 1.00, twice at 2.00, and so on. The clock takes 6 seconds to strike 5.00 and 12 seconds to strike 9.00. the time needed to strike 1.00 is negligible. How long does the clock need for all its striking in 24 hours?
a)168 Seconds
b)178 Seconds
c)188 Seconds
d) 198 Seconds
How to solve this question?

Sethil ji you are wrong. A complete rotation means 360 degree. & 2 o 'clock comes its half as in 6 position. So ans is 360/2=180 degree simple.

Rishi. Good solution.

Each hour takes 180 degree to rotate.
That's very simple concept each clock takes a complete rotation to complete an hour. So one complete rotation denotes the angle of 180 degree.
