(1) PQ= a positive multiple of 5,But here no information available for specific value of P,Insufficient
(2) we can say,3P=5Q,here no information available for specific value of P,Insufficient
(1)+(2) gives us no specific value of P,hence Insufficient

Statement 1: PQ = 5k, where k=1,2,3....so on. Insufficient to calculate value of P.
Statement 2: 3P=5Q. Clearly, Insufficient to calculate value of P.
Combining both statements: P*(3/5)P = 5k
P^2 = (25/3) k
P = 5*(k/3)^(1/2)
P is always positive as given in question stem. k can have any value as 1,2,3...... Hence, Insufficient.
