Each of the questions below consists of a question and two statements numbered (1) and (2) given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer.
Question : 1
If 8A + 9C + 2D + 3I = 106, then what is the value of I?
6A + 4C - 16D - 4E = 48
24C – 13I = 28
a) BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient.
b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
c) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
d) Statements (1) and (2) TOGETHER are NOT sufficient.
Answer »Answer: (d)
Both statements together are insufficient because the no. of unknown variables is more than the no. of equations.
Question : 2
How is 'A' related to 'B' ?
(1) A is married to Y's sister.
(2) B is the name of Y's sister.
a) BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient.
b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
c) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
d) Statements (1) and (2) TOGETHER are NOT sufficient.
Answer »Answer: (d)
Here we have not been given the number of sisters of Y in both statements. Hence, we cannot find the answer using both the statements.
Question : 3
X, Y and Z are integers. Is X an odd number?
(1) An odd number is obtained when X is divided by 5.
(2) (X + Y) is an odd number.
a) BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient.
b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
c) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
d) Statements (1) and (2) TOGETHER are NOT sufficient.
Answer »Answer: (c)
(1) ⇒ It is sufficient to answer the question because any odd number is divided by any odd number, it gives an odd number.
(2) ⇒ Either X or Y is odd ⇒ X may be odd or not.
∴ Statement (2) is not sufficient.
Question : 4
In the figure, is PRSU a square?
(1) PQ = QR and UT = TS.
(2) PU = RS.
a) BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient.
b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
c) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
d) Statements (1) and (2) TOGETHER are NOT sufficient.
Answer »Answer: (d)
By using both statements we cannot be determined PR = US.
So, both statements together are not sufficient.
Question : 5
What was the cost price of the suitcase purchased by Samir?
(1) Samir got 20 per cent concession on the labelled price.
(2) Samir sold the suitcase for Rs.2000 with 25 per cent profit on the labelled price.
a) BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient.
b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
c) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
d) Statements (1) and (2) TOGETHER are NOT sufficient.
Answer »Answer: (c)
(2) ⇒ Labelled price = ${2000}/{125}$ × 100 = Rs.1600
(1) ⇒ C.P. of suitcase = 1600$(1 - {20}/{100})$ = Rs.1280
Hence, both the statements together are necessary to answer the question.
