(1) Salary of Q is equal to the sum of salaries of P and R.

(2) Salary of R is one-third less than the salary of P.

Let the salaries of P, Q and R be P, Q and R respectively
What is asked is what percent of P's salary is Q's salary
= $$\frac{Q}{P}*100$$

Now options
(1) Salary of Q is equal to the sum of salaries of P and R.
-> Q = P + R
ask = $$\frac{Q}{P}*100$$ = $$\frac{(P+R)}{P}*100$$
still R is not known hence Not Sufficient

(2) Salary of R is one-third less than the salary of P.
-> $$R=(1 -\frac{1}{3})P$$
-> R = $$\frac{2}{3}$$P
Nothing Specified about Q hence NS

Combining the 2 is sufficient
ask Q = $$\frac{(P+R)}{P}*100$$ from 1
from 2 we know R = $$\frac{2}{3}$$P
-> P+R = P +$$\frac{2}{3}$$P = $$P*\frac{5}{3}$$
-> $$Q = \frac{5}{3}100$$
