Solution
To determine if a number is divisible by 7, double the last digit of the number and subtract it from the number formed by the remaining digits. If their difference is a multiple of 7, the number is divisible by 7.
6021 is divisible by 7.
We have 602 − 2 × 1 = 600, which is not a multiple of 7.
