plz explain in detail.

Question:
DIRECTIONS: In each of the following questions, a question is followed by information given in two statements. You have to study the question along with the statements and decide, the information given in which of the statements (s) is necessary to answer the question?

A test for M.B.A. comprised of three sections. What is the total number of questions in the test?

(A) The product of the number of questions in each section is 35,351.

(B) Number of questions in each section is greater than 20.

Options:
A) If the question can be answered by using statement I alone but not by using statement II alone
B) If the question can be answered by using statement II alone but not by using statement I alone
C) If the question can be answered by using either of the statements alone
D) If the question can be answered by using both the statements together but not by either of the statements alone
E) If the question cannot be answered even by using both the statements together
Solution:

From statements (A), the answer cannot be determined as

35351=1×667×53=1×1537×23=1 ×1219×29=23×29×53=1×1×35351.

From statements (B) also, the answer can’t be determined.

Combining statements (A) and (B), 35351= 23 × 29 × 53 and hence total number of questions 

= 23 + 29 + 53 = 105.
