Answer 2

Given:

The numbers are: (a) 42724  (b) 39065 ​

To Find:

What least number should be added to the following numbers to make them divisible by 9?

Solution:

There are two ways to make numbers divisible by any number:

Either we have to subtract the remainder from the number.

or, add the value we get from, (Divisor - Remainder) to the number.

(a) 42724

on dividing the number by 9, we get the reminder to be 1.

Therefore, as we cannot subtract 1 from the number as per the given question, we will add the value we get from (Divisor - Remainder), which would be 9 - 1 = 8, to the number to make it divisible by 9.

(b) 39065

on dividing the number by 9, we get the reminder to be 5.

Now, as we cannot subtract 5 from the number as per the given question, we will add the value we get from (Divisor - Remainder), which would be 9 - 5 = 4, to the number to make it divisible by 9.

Hence, the numbers that we have to add to make the given numbers divisible by 9 are 8 and 4 respectively.
