Question

the number 7A4B is divisible by 18 . find the possible value.of A and B​

Answer 1

Step-by-step explanation:

Divisibility rule of 18 is

the number should be divisible by 2 and 9

So we can say that the value of B should be even

and divisibility of 9 is the sum of its digits

so

7 + A + 4 + B = multiple of 9

11 + A + B = multiple of 9

let's take multiple as 18

so 11 + A + B = 18

A + B = 7

possible values of A and B are 3,4 and 5,2

so the possible answers are 7344 and 7542

Now we will take multiple of 9 as 27

so 7 + A + 4 + B = 27

11 + A + B = 27

A + B = 16

possible values only 8,8

so the possible answer is - 7848

So the possible answers are - 7344,7542 and 7848

hope it helps you
