(B) 93/12
(C) 93/13
(D) 93/10
(E) 93/8
a: Stream of consciousness: Here both numbers are less than 100. So they are deficient of - 4 and - 1 compared with 100. So The answer is (E).

question: A no.when divided by 221 gives a remainder 43, what remainder will beobtained by dividingthe same no.17?
Options:
(A) 2
(B) 7
(C) 9
(D) 11
(E) 15
answer: Stream of consciousness: 221 + 43 = 264/17 = 9 (Remainder) The answer is (C).

q: K-numbers are positive integers with only 2's as their digits. For example, 2, 22, and 222 are K-numbers. The K-weight of a number n is the minimum number of K-numbers that must be added together to equal n. For example, the K-weight of 50 is 5, because 50 = 22 + 22 + 2 + 2 + 2. What is the K-weight of 650?
Options:
(A) 10
(B) 11
(C) 12
(D) 13
(E) 14
a: Stream of consciousness: 650 = 2*222 + (22*9) + 4*2
K weight of 600 = 2 +9+2 = 13 The answer is (D).

question: Find the odd man out 4, 5, 15, 49, 201, 1011, 6073
Options:
(A) 10
(B) 7
(C) 5
(D) 2
(E) 3
answer: Stream of consciousness: 4 x 1 + 2 = 6
6 x 2 + 3 = 15
15 x 3 + 4 = 49
49 x 4 + 5 = 210 The answer is (C).

q: A train 175 m long, running with a speed of 63 km/hr will pass a tree in?
Options:
(A) 22 sec
(B) 16 sec
(C) 17 sec
(D) 88 sec
(E) 10 sec
a: Stream of consciousness: Speed = 63 * 5/18 = 35/2 m/sec
Time taken = 175 * 2/35 = 10 sec The answer is (E).

q: Out of 10 persons working on a project, 4 are graduates. If 3 are selected, what is the probability that there is at least one graduate among them?
Options:
(A) 5/9
(B) 5/4
(C) 5/1
(D) 5/6
(E) 5/2
a:
Stream of consciousness: P(at least one graduate) = 1 - P(no graduates)
(6 * 5 * 4)/(10 * 9 * 8) = 5/6 The answer is (D).
