Answer 1

Answer:

Remainder is 4

Step-by-step explanation:

If any number with last digit as 4 is divided by 5, we get remainder of 4

The no divisible by 5, it's last digit must be 0 or 5

4 is less than 5 and greater than 0,

So no with last digit as 4 divisible by 5, we always get remainder of 4

Ex remainder of 14/5=4, 24/5=4 etc
