Answer 2

SOLUTION

TO CHECK

The below statement is True or False :

561234 is a multiple of 3

CONCEPT TO BE IMPLEMENTED

1. Divisibility Rule of 3

A number is divisible by 3 if the sum of the digits of the number is divisible by 3

2. A number is said to be multiple of m if it is divisible by m

EVALUATION

Here the given number is 561234

Now sum of the digits of the number

$\sf{ = 5 + 6 + 1 + 2 + 3 + 4}$

$\sf{ = 21}$

∴ 561234 is divisible by 3 if 21 is divisible by 3

Now for the number 21 , sum of the digits

= 2 + 1

= 3

Since 3 is divisible by 3

∴ 21 is divisible by 3

∴ 561234 is divisible by 3

∴ 561234 is multiple of 3

Hence the statement is TRUE
