Question

what should be replaced with * if 9124*1 is divisible by 3 ? *​

Answer 1

Answer:-

• The rule for divisibility by 3 works for all numbers no matter how large.
• Add the digits of the number and check if this result is also divisible by 3.

9 + 1 + 2 + 4 + 1 = 17

but, it should be divisible by 3.

⇒ * = 1

so, the number will become 18, which is a divisible of 3

Answer 2

Answer:

1

1 is the answer because according to the divisibility rule of three we will add all the digits in the number that we have.

= 9+1+2+4+1

= 17

17 is not divisible by 3

So we need to find the nearest multiple of 3 that is bigger than 17 i.e. 18

So, 18-17=1

So, the number that is divisible by 3 = 912411
