Question

The smallest number that must be added to 1231 ,so that it becomes exactly divisible by 3___________​

Answer 1

Answer:

2

Step-by-step explanation:

Sum of digits of a number when divisible by 3, the number is divisible by 3.

1+2+3+1 = 7

Least no. divisible by 3 near 7 = 9

9-7 = 2

Therefore if we add 2, it will be divisible by 3

new no. = 1231+2 = 1233

1233/3 = 411

Answer 2

iAnswer:

Step-by-step explanation:

1231

1+2+3+1 = 7

SO, the closer number that is divisible by 3 is 9

so if we add 2 to the number 1+2+3+1 + 2 = 9

The smallest number that must be added to 1231 ,so that it becomes exactly divisible by 3 is 2

hope it helps
