Total marks obtained by P, Q, R and S in Mathematics is 360. How many marks did P secure in Mathematics?
I. P secured one-third marks of the total of Q, R and S.
II. Average marks obtained by Q and R are 20 more than that secured by S.

- if statement I alone is sufficient to answer the question.
- if statement II alone is sufficient to answer the question.
- if both statement I and II together are necessary to answer the question.
- if both statement I and II together are not sufficient to answer the question.
- if statement I alone is sufficient to answer the question.
Correct Option: A
Since sum is 360 hence P + Q + R + S = 360
From statement I alone we will get P = (Q + R + S)/3 from this we can find the value of P hence statement I alone is sufficient enough.
From statement II alone we can not find the value of P.
