Show answer & explanation
Correct answer: C
Explanation
Given:
Numbers = 8235, 8491, 10320, 7582
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
8235 → (8+2+3+5 = 18), (35 ÷ 4) ⇒ No
8491 → (8+4+9+1 = 22) ⇒ No
10320 → (1+0+3+2+0 = 6), (20 ÷ 4) ⇒ Yes
7582 → (7+5+8+2 = 22) ⇒ No
