question: If 8m − n = p, then which of the following represents the average (arithmetic mean) of m, n, and p, in terms of m?
Options:
(A) 2m −1
(B) 3m
(C) 6m
(D) m/5
(E) 6m/5
answer: Stream of consciousness: 8m - n = p
Add n to both sides:
8m = n + p
Add m to both sides:
9m = n + p + m
Now, divide both sides by 3
3m = (n + p + m)/3 = the average of n, p, and m The answer is (B).


q: How many terminating zeroes T does 200! have?
Options:
(A)  40
(B)  48
(C)  49
(D)  55
(E)  64
a: Stream of consciousness: You have 40 multiples of 5, 8 of 25 and 1 of 125. This will give 49 zeros. The answer is (C).


question: How much 60% of 50 is greater than 40% of 30?
Options:
(A) 18
(B) 91
(C) 11
(D) 17
(E) 12
answer: Stream of consciousness: (60/100) * 50 – (40/100) * 30
30 - 12 = 18 The answer is (A).


q: Find the value of y from (12)^3 x 6^4 ÷ 432 = y?
Options:
(A) 4556
(B) 2354
(C) 4576
(D) 6768
(E) 5184
a: Stream of consciousness: Given Exp. = (12)3 x 64 = (12)3 x 64 = (12)2 x 62 = (72)2 = 5184
432 12 x 62 The answer is (E).

Options:
(A) 15
(B) 66
(C) 77
(D) 88
(E) 12
answer: Stream of consciousness: 90 * 10/60 = 15 kmph The answer is (A).

Options:
(A) 220060
(B) 145778
(C) 220050
(D) 220800
(E) 220030
