Question

A number of the form 5834*24 is divisible by
8. The lowest possible value of * is​

Answer 1

Answer :

The given number is 5834*24

Let, * be the x ,

the number become 5834x24

=> Divisibility rule of 8 : alternate adding and subtracting the digits , and if the result is multiple of 8 , then the original number is the multiple of 8.

=> ( 5 + 3 + x + 4 ) - ( 8 + 4 + 2 )

= x -2

=> x - 2 = 8

=> x = 10

=> 10 is the least value must be given to * so that the number 583424 is divisible by 8

Answer 2

Answer:

The lowest possible value of * is​ 0.

Given:

a number 5834*24

To find:

The lowest possible value of *

Solution:

the divisibility rule of 8:

if the last three digits of a number are divisible by 8, then the entire number is divisible by 8.

to find the lowest possible value of *, we need to substitute the values in 5834*24 in increasing order.

• putting the smallest number in place of *, i.e. 0

let 5834024 be divisible by 8.

now since 024 is divisible by 8, therefore, 5834024 will also be divisible by 8.

5834024 / 8 = 729,253.

Hence, 0 is the lowest possible value of *.
