Statement 1

The product of any 4 consecutive numbers is definetly divisible by 3.

Take exampes 1.2.3.4 , 2.3.4.5 , 11.12.13.14 etc etc.. Each of these products is definetly divisible by 3.

Hence statement 1 is sufficient

Statement 2

r= 7(not divisible by 3)
r=6 (divisible by 3)

Hence statement 2 is not sufficient.

Ans - A

Statement 1 would be better phrased as "four consecutive integers."
