Ans. 
The time taken for the clock to tick from 8'o clock to 11'o clock is 105 seconds.
• Each tick represents 1/8th of an hour (45 minutes) on the clock.

• From 8'o clock to 11'o clock, there are 3 hours, so the total time taken is 3 * 45 = 135 minutes = 135 * 60 = 8100 seconds.

• The time taken for the clock to tick from 8'o clock to 11'o clock is 8100 - 35 = 8065 seconds.
