(C) A number is divisible by 3 if its unit digit is divisible by 3. (D) A number is divisible by 4 if the number formed by its last two digits is divisible by 4. Choose the correct answer from the options given below: |
(A), (B) and (D) only (B) and (D) only (A), (C) and (D) only (B) and (C) only |
(B) and (D) only |
The correct statements for divisibility are: (A) A number is divisible by 6 if it is divisible by 3 and 2 both (Not by 3 or 2), because LCM of 2 and 3 is 6. (B) A number is divisible by 5 if its unit digit is 0 or 5 = All numbers with last digit 5 and 0 are divisible by 5. C) A number is divisible by 3 if sum of the digits of the number is divisible by 3 not the unit digit. (D) A number is divisible by 4 if the number formed by its last two digits is divisible by 4 = Number is divisible by 4 if its last 2 digit are divisible by 4. So, the correct answer is: (B) and (D) only |
