Question

4. Which of the following is divisible by 3?
a) 8345
b) 102358
c) 6732
d) 1001​

Answer 1

Answer:

C) Is the correct answer.

Step-by-step explanation:

We know that divisibility of 3 is checked by adding all the digits of the number and checking the sum of the number is 3.

a)8345

First we will add the digits.8 + 3 + 4 + 5 = 20.

We got the sum as 20.Now check whether 20 is a multiple of 3.We find that 20 is not a multiple of 3.

So the number 8345 is not divisible by 3.

(b)102358

First we can add the digits of the number.1 + 0 + 2 + 3 + 5 + 8 = 19.Check whether 19 is a multiple of 3.We find that 19 is not a multiple of 3.

So the number 102358 is not a multiple of 3.

(C)6732

First we will add the digits of the number.6 + 7 + 3 + 2 = 18.Check whether 18 is a multiple of 3.We find the it is a multiple of 3.

Therefore 6732 is divisible by 3

(D)1001

First we will add the digits of the number.1 + 0 + 0 + 1 = 2.Check whether 2 is a multiple of 3.We find that the number 1001 is not a multiple of 3.

Therefore 1001 is not divisible by 3.

Answer 2

Answer:

if the sum of number s divisible by 3 then the the number is also divisible by 3

Step-by-step explanation:

a _ 8+3+5+4=20

b= 1+0+2+3+5+8=19

c=6+7+3+2=18

d=1+0+0+1=2

here only sum of option is divisible by 3

So Option C is correct answer
