Question

Take out the mean of the ages 12 years, 13 years, 12 years 3 months, 12 years 6 months, 12years and 9 month, 13 years 3 months, 13 years 3 months, 12 years 6 months 12, and 13 years 6 months​

Answer 1

Average age is 12 years and 3 months
1 year is having 365 days (assuming only in leap year)
1 day is having 24 hour
1 hour is 60min
1 min is 60 second
Now doing all these in reverse order,
1 hour = 60×60 second
1 day = 24×60×60 second
1 year = 365×24×60×60 second
So, 12 year = 12×365×24×60×60 second = 378432000 sec
1 months = 30 days
3 months will be 3×30 days
= 3×30×24×60×60 second = 7776000 sec
12 years and 3 months = 378432000 + 7776000
= 386208000 second
