Question

Test the divisibility of each of the following numbers by 4:

Answer 1

Answer:

A number is divisible by 4 if the number is formed by its digits in ten’s place and unit’s place (i.e. the last two digits on its extreme right side) is divisible by 4.

Consider the following numbers which are divisible by 4 or which are divisible by 4, using the test of divisibility by 4:

(i) 124

In 124 the last two digits on its extreme right side is 24 which is divisible by 4.

Hence, 124 is divisible by 4.
