S1 - Insufficient. P and E can have multiple values.
S2 - Insufficient. Same as above.

(S1 + S2)
P = E - 20,000
E = 3P
Substitute and a single value can be derived => Sufficient.

C is the answer.

Very simple just use algebra

Statement 1

Obviously not - P =E-20,000

Statement 2

Obviously not - you would just get e =3p

Statement 1 and 2

E=3p
P =E-20,000 substitute

2p= 20000 done
