(1) When p is divided by 12, the remainder is 7.
Possible value of P = 7, 19, 31, 43....
All of the values of p will leave the remainder 1 when p is divided by 3
Therefore, Statement 1 is sufficient
(2) p = n(n + 1) + 1, where n is an integer.
if n = 1
p = 3
then p/3 = 0
if n = 2
p = 7
then p/3 leaves 1 as the remainder.
Therefore, Statement 2 is not-sufficient
