Insufficient 1 & 2 together. \(RQ = P^3  (P2)^3\) So \(P^3\)gets cancelled out and we only have multiples of 3 and a constant remaining. Sufficient Answer is C. Kudos Please... If my post helped.

Hi folks, Both are insufficient without any doubts checking for option (C). P=3 , P2 =1 271 = 26/3 =2 P=4 , P2 = 2 648 = 56/3 =2 P=5 , P2 = 3 12527 , Rem=2 P=6, P2 = 4 Rem =2 Hence (C)
