Question

what the least number should be subtracted from 6709 to make it divisible by 9

Answer 1

To be divisible by 9 sum of all digits should be divisible by 9.
= 6+7+0+9 = 22 ( not divisible by 9)
subtract 4 from 22 will satisfy the condition.
So subtract 4 from 6709 , which is 6705 which is perfectly divisible by 9.
Hope it helps.
Have a great day.
