Answer 2

Answer :

The minimum value of A+B is 6.

Step by step explanation :

Hey Mate,

We need to find the value of A & B from the number 9A987B6 which divisible by 18.

Divisibility Rule of 18 : A number which can divide by 2 and 9 both. Then the number is also divided by 18.

Divisibility Rule of 2 : If the unit digit of any number divided by 2. Then the whole number can divided by 2.

Divisibility Rule of 9 : If the sum of all digit of number is divisible by 9. then the whole number is divided by 9.

So,  

9 + A + 9 + 8 + 7 + B + 6 = 39.

Next number after 39 which divided by 9 is 45.

So,

The minimum value of A+B is 6.
