Answer:

please solve it options are (a) 2 (b) 3 (c) 6 (d) 9

Answer 2

Answer:

Option (3) 3 is the correct answer .

Step-by-step explanation:

Explanation:

Given a number which is 28221 .

A number is  divisible by 2 , if the last digit number be 0,2,4,6, and 8

A number is divisible by 3 , when the sum of the digit should be divisible by 3 .

A number is divisible by 4 , if  the last two digit  number is divisible by 4

And a number is divisible by 9 , if the sum of its digit should be divisible by 9 .

Step 1:

• 28221 is not divisible by 2 because last digit  of the given number is 1 .

• The last two digit   number of  28221 is 21 and 21 is not divisible by 4 . Therefore , 28221 is not divisible by 4 .
• And the sum of the digit of the given number is ,  2+8+2+2+1 = 15  and 15 is not divisible by 9 , so 28221 is also not   divisible by 9 .

• But 15 is divisible by 3 , 28221 is divisible by 3 because sum of the digit its digit is divisible by 3 .

Final answer:

Hence, 28221 is divisible by 3
