Which of the following has the most number of divisors?

A.
99
B.
101
C.
176
D.
182

Your Answer: Option (Not Answered)

Correct Answer: Option C

101 = 1 x 101

176 = 1 x 2 x 2 x 2 x 2 x 11

182 = 1 x 2 x 7 x 13

So, divisors of 99 are 1, 3, 9, 11, 33, .99

Divisors of 101 are 1 and 101

Divisors of 176 are 1, 2, 4, 8, 11, 16, 22, 44, 88 and 176

Divisors of 182 are 1, 2, 7, 13, 14, 26, 91 and 182.

Hence, 176 has the most number of divisors.

Thus, I alone gives the answer.

II. a = 8 m       Volume = (8 x 8 x 8) m3 = 512 m3.

Thus, II alone gives the answer.

Correct answer is (C).

B.
2011
C.
2012
D.
2013

Your Answer: Option (Not Answered)

Correct Answer: Option B

Explanation:

Suppose commodity X will cost 40 paise more than Y after z years.

Then, (4.20 + 0.40z) - (6.30 + 0.15z) = 0.40

0.25z = 0.40 + 2.10

z = 2.50 = 250 = 10.
0.25 25

X will cost 40 paise more than Y 10 years after 2001 i.e., 2011.

Correct Answer: Option C

Explanation:

.__________.______________________________________.
A     x    C            (100 - x)                 B       

Let AC = x km. Then, CB = (100 -x) km.


 I. AB = 125% of CB

100 = 125 x (100 - x)
100

100 - x = 100 x 100 = 80
125

x = 20 km.

AC = 20 km.

Thus, I alone gives the answer.


II. AC = 1 CB
4

x = 1 (100 - x)

5x = 100

x = 20.

AC = 20 km.

Thus, II alone gives the answer.

III. S.P. = 90% of M.P.

Thus, I and III give, S.P. = Rs. 90 x 13x = Rs. 117x
100 10 100

Gain = Rs. 117x - x = Rs. 17x
100 100

Thus, from I and III, gain % can be obtained.

Clearly, II is redundant.
