If 1 hour has 3600 seconds then how many seconds are there in 1 century

One century contains 100 years i.e. 25 leap year and 75 non-leap year

= 25 years with 366 days and 75 years with 365 days.

⇒ Days in one century = 25 × 366 + 75 × 365

= 9150 + 27375 = 36525

Now hours in one day = 24

⇒ hours in one century = 24 × 36525 = 876600

Given : Seconds in one hours = 3600

⇒ Seconds in one century = 3600 × 876600 = 3155760000

Hence there are 3155760000 seconds in one century.
