City X has two libraries. Does the total number of books in both the libraries exceed 18,000 ? Statements :
I. One library has twice as many books as the other library.
II. One library has 9000 books.
A :
If statement I alone is sufficient but statement II alone is not sufficient to answer the question.
B :
If statement II alone is sufficient but statement I alone is not sufficient to answer the question.
C :
If both the statements I and II together are sufficient to answer the
question but neither statement alone is sufficient to answer the
question.
D :
If I and II together are not sufficient to answer the question and additional information is required.
Answer: D It is not given that which library contains 9,000 books. Let, the library contains maximum books 9,000 Thus, total number of books = 9000 + 4500 = 13500. Let the library contains minimum books = 9,000 Thus, total number of books = 9,000 + 18000 = 27,000. Hence, we can't said anything it will be greater than or less than 18,000.
Q. No. 26:
How many minutes does the clock lost a day ? Statements :
I. The clock reads 6:00 when it really 5:48.
II. The clock is 40 second fast each hour.
A :
If statement I alone is sufficient but statement II alone is not sufficient to answer the question.
B :
If statement II alone is sufficient but statement I alone is not sufficient to answer the question.
C :
If both the statements I and II together are sufficient to answer the
question but neither statement alone is sufficient to answer the
question.
D :
If I and II together are not sufficient to answer the question and additional information is required.
Answer: B Statement I : It does not give the rate of time lost by the clock. Hence, we cannot get the time lost by it in 24 hours i.e a day. Statement II : The clock lost = 24*40 = 960 seconds a day. Hence, Statement II sufficient to answer the question.
Q. No. 27:
How many tonnes of cement will be needed for the foundation of an apartment building ? Statements :
I. The entire building will require 5000 tonnes of cement.
II. The volume of the cement needed for the foundation is 1000 cubic yards.
A :
If statement I alone is sufficient but statement II alone is not sufficient to answer the question.
B :
If statement II alone is sufficient but statement I alone is not sufficient to answer the question.
C :
If both the statements I and II together are sufficient to answer the
question but neither statement alone is sufficient to answer the
question.
D :
If I and II together are not sufficient to answer the question and additional information is required.
Answer: D Statement I : No value about the requirements for the foundation of the apartment. Statement II : There is no information about the density of the cement. Hence, both statement together are not sufficient to answer the question.
Q. No. 28:
If t is a multiple of prime number S, is t a multiple of S2 ?
Statements : I. S < 4 II. t = 18
A :
If statement I alone is sufficient but statement II alone is not sufficient to answer the question.
B :
If statement II alone is sufficient but statement I alone is not sufficient to answer the question.
C :
If both the statements I and II together are sufficient to answer the
question but neither statement alone is sufficient to answer the
question.
D :
If I and II together are not sufficient to answer the question and additional information is required.
Answer: C Statement I : S = 2,3 and S*S = 4, 9. Then fr S = 2, 3t = 4,6 and 6,9 Clearly, t may be a multiple of S2 but not of S. Statement II : t =18. Then from I and II, S= 3, S2 = 9. Now 18 is the multiple of S and S2 . Hence both I and II are required to solve the question.
Q. No. 29:
A group of 49 consumers were offered a chance to subscribe to at least one of the three magazines. How many of the 49 consumers subscribed to exactly two of the magazines ?

C :
If both the statements I and II together are sufficient to answer the
question but neither statement alone is sufficient to answer the
question.
D :
If I and II together are not sufficient to answer the question and additional information is required.
Answer: D Since data is not given for all 49 consumers so we cannot find the required answer even using both the statements.
