q: If N is the least positive integer that is divisible by every integer from 3 to 10 inclusive, then N/7 is =
Options:
(A) 360
(B) 720
(C) 2520
(D) 3960
(E) 6720
a: Stream of consciousness: The integer should be divisible by: 3, 4, 5, 6, 7, 8, 9 and 10, that is 3, 2^2, 5, 2*3, 7, 2^3, 3^2, 2*5. The least common multiple of these integers is the product of 7, 5, 3^2 and 2^3. Then, N/7 is (7 * 5 * 3^2 * 2^3)/7 = 5*9*8 = 360. The answer is (A).

q: Find the odd man out
4, 10, 22, 40, 84, 94
Options:
(A) 22
(B) 40
(C) 94
(D) 84
(E) 10
a: Stream of consciousness: Differnce is multiple of 6
4 and 10 diff is 6
10 and 22 diff is 12
22 and 40 diff is 18
40+24 = 64 but in series it is mentioned as 84
64+30 = 94 The answer is (D).

(A) 33 1/8%
(B) 33 1/3%
(C) 33 7/3%
(D) 32 1/3%
(E) 12 1/2%
answer: Stream of consciousness: P = (P*8*R)/100
R = 12 1/2% The answer is (E).

q: A train 540 meters long is running with a speed of 54 kmph. The time taken by it to cross a tunnel 180 meters long is?
Options:
(A) 40
(B) 48
(C) 45
(D) 50
(E) 25
a: Stream of consciousness: D = 540 + 180 = 720
S = 54 * 5/18 = 15 mps
T = 720/15 = 48 sec The answer is (B).
