Question

What is the numerical value of
a if the number 476a7b2 In
divisible by 9 ?

​

Answer 1

Answer:

Step-by-step explanation:

It will be dependent on b.

Answer 2

Here the sum of every digit should be a multiple of 9

then, 4+7+6+a+7+b+2=26+a+b

so a+b should be equal to 1 so that sum of digit should get equal to 27 which is a multiple of 9

therefore a+b=1

a=1-b
