The average age of children in Class VII is 12 years and 3 month

We know that there are 365 days in a year and 30 days in a month.

So, average age of children in days $=(12\times365+3\times30)\ days$

$=(4380+90)\ days$

$=4470\ days$

$=4470\times 24\ hour$              [There are 24 hours in a day]

$=1,07,280\ hours$

$=1,07,280\times 60\times60\ seconds$     [Because $1\ hour=60\times60=3600\ seconds$]

$=38,62,08,000\ seconds$

Therefore, the average age of children of class VII is $38,62,08,000\ seconds$.
