Question

Replace * in the number 8 4 5 * 6 to make the number exactly divisible by 4.

Answer 1

Answer:

84516 is the number which will be exactly divisible by 4.

Answer 2

Answer:

Given that, the number 66784∗ is divisible by 9.

To find out: The smallest value of ∗.

We know that, a number is divisible by 9, if the sum of its digits is divisible by 9.

The sum of digits of the give number =6+6+7+8+4+∗

⇒31+∗

The smallest number after 31 which is divisible by 9 is 36.

Hence, for the smallest value of ∗, the sum of digits should be 36.

∴ 31+∗=36

⇒∗=36−31=5

Hence, the smallest value of ∗ for which the number 66784∗ is divisible by 9, is 5.
