Which of the following number is divisible by both 4 and 9?
Show answer & explanation
Correct answer: C
Explanation
Given:
The number must be divisible by both 4 and 9.
According to the rules:
Divisibility by 4 ⇒ The last two digits must be divisible by 4.
Divisibility by 9 ⇒ The sum of the digits must be divisible by 9.
1940 → 40 ÷ 4 = Integer; 1+9+4+0 = 14 (Not divisible by 9)
1981 → 81 ÷ 4 = No
2016 → 16 ÷ 4 = 4; 2+0+1+6 = 9 (Divisible by 9)
2090 → 90 ÷ 4 = No
