It will depend on the denomination(s). For example, it will take a hundred times longer to count in 5 rupee notes than in 500 rupee notes!
1 billion seconds?
2 billion seconds
To count one billion objects, it would take you however long it takes to count one object times one billion. It does not matter how much mass the object has, so your statement of mass is meaningless.
If you counted 1 number per second, it would take 63 years to count to 2 billion.
If you counted 1 number per second, it would take 3200 years to count to 100 billion.
If you counted 1 number per second, it would take 220 years to count to 7 billion.
4.5 billion seconds.
If you counted 1 number per second, it would take at least 220 years to count to 6.9 billion.

I recall reading that it would take you 3 weeks to count to a million if you counted all day, taking time off to eat and sleep. So to count to a billion would take 1000 times 3 weeks.
It really depends with the speed of the person counting. There is no definite time frame to count from 1 to 100 billion.
well it dapends how fast u count but i can count out 120 in a min so 60 billion/120=ur aunswer
