Answer:
80 four-digit numbers are there which is divisible by 4.
Explanation:
Consider the provided information.
A number is divisible by 4 if the last 2 digits are divisible by 4.
So the possible last 2 digits are:
xx12, xx24, xx32, xx44, xx52
In each case, for first two number we have 4 choices and last 2 choices are fixed.
Therefore, the total number of ways are: 5(4×4)
Where 5 represents possible case in which last 2 digits are divisible by 4.
the total number of ways are: 5(4×4)=80
Hence, 80 four-digit numbers are there which is divisible by 4.
