1.06p > q ???

Statement I

q-p < 50
q < 50+p

We dont know the value of q or p to determine which amount is greater or smaller.

Insufficient.

Statement II

q=1150

we dont know the value of p.

Insufficient.

Combining I & II

1150 - p < 50

1100 < p

Even if take p=1100

1.06 p = 1166 > q=1150

Sufficient.

Hence C.

Hope this helps.
