Question

If a number of three - digits 24x ‚ is divisible by 9 ‚ then find the value of x where is digit . ​

Answer 1

x is 3

this is because the nber 243 is when divided by 9 leaves remainder zero

Answer 2

Given number is 24x

So , sum of digits = 2+4+x = 6 + x

It must be divide by 9 but it is possible if 6-x is either 9 or 18 .

Then x = 9 - 6 = 3

If 6+x = 18, x= 18-6 = 12

Here,x is a digit, so x is not 12

Hence , x = 3
