Solution
The correct options are
A 2
B 3
D 6
The numbers will completely divide 324, if they satisfy the divisibility rule.
Divisibility by 2
As 324 is an even number, it is divisible by 2.
Divisibility by 3
Since sum of digits, 3 + 2 + 4 = 9, is divisible by 3, 324 is also divisible by 3.
Divisibility by 5
324 is not divisible by 5 because for a number to be divisible by 5, ones digit should be either 5 or 0.
Divisibility by 6
Since 324 is divisible by both 2 and 3, it is also divisible by 6.
∴ 324 is divisble by 2, 3 and 6.
