Question

Replace * by the smallest number, so that the number 1*1 is divisible by 3.

• A. 3
• B. 1
• C. 4
• D. 2

Answer 1

The correct option is B

1

Here, Sum the known digits of 1*1 = 1 + 1 = 2

Now the number next to 2, which is divisible by 3 is 3.

Thus if we replace the * by 1 the sum of digits will become 3 and the number becomes divisible by 3.
