Find the value of a+b+c if 673a is divisible by 15,673b is divisible by 7 and 673c is divisible by 3...

11

Step-by-step explanation:

The divisibility rule of 15 is if the number is divisible by both 5 and 3

The divisibility rule of 3 is if the sum of all digits is divisible by 3

The divisibility rule of 5 is if the number ends with 0 and 5

So 6735 is divisible by 15, so A=5

Well, I really don't know the divisibility rule of 7

But, 6734 is divisible by 7, so B=4

The divisibility rule of 33 is if the number is both divisibile by 3 and 11

The divisibility rule of 11 is if the alternative digits of the number

is equal

So it's, 6732, so C=2

Add them together,

5+4=9

9+2=11
