Counta within a range of numbers

Can you work out a formula for the following scenario?

A cell that will count an entry in another cell, within a range of numbers.

EX:

cell g1 will count the entries that range from 1000 to 1999 and 5000 to 5999 and 7000 to 7999.

cell h1 will count the entries that range from 2000 to 2999 and 6000 to 6999 and 8000 to 8999.

So if i had 6 cells with the following entries:

cell a1 - 1010
cell b1 - 2230
cell c1 - 5699
cell d1 - 6521
cell e1 - 7001
cell f1 - 8035


cell g1 would show 3
cell h1 would show 3
