Answer: without trying each calculation individually, 6750 4-digit numbers are not divisible by 4

Step-by-step explanation: From 1000 to 9999 there are 9000 4-digit numbers 9999 - 999 = 9000.

Eliminate all the odd numbers 9000/2 = 4500

Eliminate the even numbers divisible by 2 but not by 4. 4500/2 = 2250

9000 - 2250 = 6750.
