Is p < q ?
(1) 1/3*p < 1/3*q
(2) –p + x > –q + x
(1) 1/3*p < 1/3*q
(2) –p + x > –q + x
(1) 1/3*p < 1/3*q
Cancel 1/3 from both sides....then p < q
Sufficient
(2) –p + x > –q + x
Cancel x from both sides....then -p > -q
Multiply both sides y -1...then p < q
Sufficient
Answer: D

(1) 1/3*p < 1/3*q
(2) –p + x > –q + x
Q: Is p<q?
S1:
1/3*p < 1/3*q
=> p<q
SUFFICIENT
S2:
–p + x > –q + x
-p >-q
p<q (multiply by -1)
SUFFICIENT
IMO D
