Given: rp=q
Find: pq - ?
1) \(4rp^2\) = 64 (divide by 4)
\(rp^2\) = 16
Since given that rp=q, then r = q/p
q/p x \(p^2\) = qp = 16
SUFFICIENT
2) 4q = 16
q = 4
rp=4
NOT SUFFICIENT

Start with Easy #2. q=4, we don't know the value of p so definitely insufficient.
#1. 4*r*p*p = 64
4 * q * p = 64
qp= 16, Sufficient

Given rp = q, what is the value of pq?
(1) 4rp^2 = 64
(2) 4q= 16
(1) 4rp^2 = 64
(2) 4q= 16
