Which of the following number is neither divisible by 3 nor by 4?
Show answer & explanation
Correct answer: D
Explanation
Given:
Numbers = 1272, 1236, 3420, 1265
According to the rules:
Divisibility by 3 → The sum of the digits is divisible by 3
Divisibility by 4 → The last two digits are divisible by 4
1272 → (1+2+7+2)=12, 72
1236 → (1+2+3+6)=12, 36
3420 → (3+4+2+0)=9, 20
1265 → (1+2+6+5)=14, 65
1265 (is not divisible)
