Question

Please answer me 1. if 3 digit number 24x is divisible by 9 then find the value of x. where X is a digit 2. if 3 digit number 89y is divisible by 9. then find the value of Y . ​

Answer 1

Answer:

A number is divisible by 9 if the sum of the digits are evenly divisible 9.

So, in our case it should be

2+4+x = 9

x = 9–4–2

x = 3.

So result is 243.

BTW there are also rules for another numbers like 2, 3, 5, 11

Step-by-step explanation:

Answer 2

Answer:

If we let x = 21 then 2421 is divisible by 9 so, X = 21.

If we let y = 1,then 891 is divisible by 9,so y = 1.
