Question

in each of the following numbers replace * by the smallest numbers to make it divisible by 9 53*88

Answer 1

The number given is 53*88 and * should be replaced by smallest number so that the resultant number must be divisible by 9.

If we put zero, one and two turn by turn, we will get a non-zero remainder.

But if we replace * by 3, then the remainder will be zero. This implies that the smallest number that must be included in 53*88 is 3 to make it divisible by 9.
