Direction: The following questions are based on the five three-digit numbers given below:
684	512	437	385	296

If 2 is added to the first digit of each of the numbers how many numbers thus formed will be divisible by three?

A)  None               

B)  One                

C)  Two                            

D)  Three

E)  None of these

Correct Answer: B

Solution :

The new numbers become: If the sum of digits of a number is divisible by 3 then the number is also divisible by 3. So, sum of digits of the number\[585\to 5+8+5=18\]. Hence only one such number can be formed.
