Answer 2

Answer:

Step-by-step explanation:

Divisibility Test for 3: If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.

(A) 7564

Sum of digits = 7+ 5+ 6+ 4 =22

22 is not divisible by 3 hence, 7564 is not divisible by 3

(B) 984349

Sum of digits = 9+8+4+3+4+9 = 37

37 is not divisible by 3 hence, 984349 is not divisible by 3
