q: Interest Rate: 4% monthly Starting Balance: 124 Time Passed: 4 months How much interest has accrued if calculated as compound interest? What is the new total balance?
Options:
(A) 21 & 145
(B) 22 & 146
(C) 23 & 145
(D) 20 & 140
(E) None
a: Stream of consciousness: Compound Interest: Total Balance = P(1 + R)T P = principle = starting balance = $124 R = interest rate = 4% T = time = 4 years Total balance = principle (1 + interest rate)time = 124 (1 + (4 / 100))4 = 145 Interest accrued = total balance - starting balance = 145 - 124 = 21 The answer is (A).

question: If n is an integer, then the least possible value of |35 - 6n| is?
Options:
(A) 2
(B) 3
(C) 5
(D) 0
(E) 1
answer: Stream of consciousness: |35 - 6n| represents the distance between 35 and 6n on the number line. Now, the distance will be minimized when 6n, which is multiple of 6, is closest to 35. Multiple of 6 which is closest to 35 is 36 (for n = 6), so the least distance is 1: |35 - 36| = 1. The answer is (E).

q: In case K is the only individual sewing on committee B, which among the following shouldserve on committee A?
Options:
(A) V and U
(B) V and T
(C) U and S
(D) L and M
(E) T and U
a: Stream of consciousness: L and M should serve on A The answer is (D).

question: During a particular baseball game, the probability of a team's pitcher throwing a strike on each throw is 2/5. What is the least number of times that the pitcher should pitch the ball that will increase the probability of getting a strike at least once to more than 50%.
Options:
(A) 3
(B) 2
(C) 1
(D) 4
(E) 5
answer: Stream of consciousness: Rule of Subtraction: P(A) = 1 - P(A')
Rule of Multiplication: P(A B) = P(A) P(B)
The probability that the pitcher throws a strike at least once in 2 guesses is 1- (3/5)^2 = 1 - 9/25 = 16/25 > 50%. The answer is (B).

q: What approximate value should come in place of question mark (?) in the following equation
287.532 + 1894.029 757.48 = 443.095 + ?
Options:
(A) 870
(B) 790
(C) 680
(D) 770
(E) 890
a: Stream of consciousness: ? = 285 + 1895 755 745 or, ? = 680 The answer is (C).

q: Find the value of y from (12)^3 x 6^4 432 = y?
Options:
(A) 2356
(B) 3454
(C) 4656
(D) 3456
(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).
