You are given that p,q>0. The question asks you what percent of p is q ---> lets say q= r% p ---> q=rp/100 ---> r=100q/p or for our purpose what is q/p = ? .

So any statement that gives you this ratio will be sufficient to answer the question.

Per statement 1, p=0.09q ---> q/p = a unique value. Sufficient.

Per statement 2, p+q=760. Clearly insufficient. You can assign values to p and q and see you end up getting different values for q/p or p/q.

2 cases, p=1, q=759, q/p = 759 but if p=759, q=1 --> q/p = 1/759. Thus you end up getting 2 different values for q/p.

Hence A is the correct answer.

Hope this helps.

We need to find out what % of p is q.

Let the unknown % be r%.

p*r%=q
r/100=q/p

(1) p=0.90q
100/90=q/p
From here we get the unique value of q/p.
We can put the value and get the value of r% which is the required answer.
Sufficient.
(2) p+q=760.

We cannot get any unique values of p and q from here.
Not Sufficient.
A

(1) p = 0.90q

q/p = 10/9; SUFFICIENT.

(2) p + q = 760

Clearly not able to solve for p or q; INSUFFICIENT.

Answer is A.
