Which of the following number is divisible by both 3 and 8?
Show answer & explanation
Correct answer: C
Explanation
Given:
Numbers = 4260, 4016, 4128, 3412
According to the rules:
Divisible by 3 ⇒ The sum of the digits is divisible by 3
Divisible by 8 ⇒ The last 3 digits are divisible by 8
4260 → 4+2+6+0 = 12 (Divisible by 3), 260 ÷ 8 = Remainder ⇒ No
4016 → 4+0+1+6 = 11 (Not divisible by 3) ⇒ No
4128 → 4+1+2+8 = 15 (Divisible by 3), 128 ÷ 8 = 16 ⇒ Divisible
3412 → 3+4+1+2 = 10 (Not divisible by 3) ⇒ No
