Question

What least nuber should be added to the least number of four digits, so that the resulting number is exactly divisible by 89.??

Answer 1

The least 4 digit number is 1000.

If we divide 1000 by 89 we get 11.23 whose integer part is 11.

and 11*89=979

979+89=1068

So 1068-1000=68 should be added to 1000 to make it divisible by 89.
