4. (i) and (ii) none

Answer 1

Given:

Two numbers (i) 541326 and (ii) 5967013.

To find:

Numbers which are divisible by 3.

Solution:

According to the divisibility rule of 3, a number is divisible by 3 if the sum of all the digits of that number is divisible by 3.

(i) Let's take the first number 541326.

Now, we will add all the digits of this number.

We have

5 + 4 + 1 + 3 + 2 + 6

= 21

As 21 is divisible by 3, so we can say that 541326 is divisible by 3.

(ii) Now, we will take the second number 5967013 and add all its digits.

We have

5 + 9 + 6 + 7 + 0 + 1 + 3

= 31

As 31 is not divisible by 3, so the number 5967013 is also not divisible by 3.

Hence, the number that is divisible by 3 is 541326.

The correct option is- 2. (i) only.
