C :
If the data either in statement I or statement II alone are sufficient to answer the question

If the data in both statements I and II together is necessary to answer the question.
Answer: D Statement I : gives us information about common difference which is 3.(d=3) Statement II : If we considering the 1st term a. The 10th term = a+ 9d. On combining, 29 = a + 9*3 a = 2. The 57th term = a +56d = 2 + 56*3

Q. No. 192:
Let PQRS be a quadrilateral. Two circles O1 and O2 are inscribed in triangle PQR and PSR respectively. Circle O1 touches PR at M and circle O2 touches PR at N. Find the length of MN. I. A circle is inscribed in the quadrilateral PQRS. II. The radii of the circles O1 and O2 are 5 and 6 units respectively.
A :
Statement I alone is sufficient to answer the question
B :
Statement II alone is sufficient to answer the question
C :
Statement I and Statement II together are sufficient, but neither of the two alone is sufficient to answer the question
D :
Neither statement I or statement II is necessary to answer the question
Answer: A Let PD=a, QD=b, RM=c, PA=d, SA=e Now, PA=PN+MN, QD=QC RC=RN+RM, RM=RB and SD=SB PS=d+e, SR=e+c, QR=b+c+MN, PQ=a+b In the second quadrilateral, PQ+SR = PS+QR x1 +x4+ x2 +x3 = x1 +x2+x3 +x4 a+b+e+c=d+e+b+c+MN a=a+MN+MN => MN = 0 So, the measure of MN can be answered can be answered from statement I alone. Thus statement I alone is sufficient. Statement II alone is not sufficient.
