Question : Which smallest number must be added to 100, so that the resulting number is completely divisible by 6?
Option 1: 2
Option 2: 3
Option 3: 5
Option 4: 4
Correct Answer: 2
Solution :
Divisibility rule of 6: The number should be divisible by both 2 and 3.
The next nearest number to 100 that is divisible by both 2 and 3 is 102.
Thus, 2 is added to 100 to get a number that is divisible by 6.
Hence, the correct answer is 2.
