only 57 satisfies the req

IMO C.

The average of three consec nos (Sum/3) should be the second integer.

Only the third option is divisible by 3.

It is a good question. :)

The approach suggested by Manulath is the approach that needs to be used for these problems

x,x+1,x+2

x+x+1+x+2 = 3x+3 = 3 (x+1)

This shows that the sum must be a multiple of 3 and the only one that fits this condition is 57
