Avinash covers a distance of 8km in 50 minutes. If he covers 3km distance in 2/5th of time then, What speed should he maintain to cover the remaining distance in the remaining time?
Options:
(A) 10 Kmph
(B) 15 Kmph
(C) 25 Kmph
(D) 27 Kmph
(E) 30 Kmph
Answer and stream of consciousness: (B)
Stream of consciousness: Total distance = 8 Km
Total time = 50 Km
Time taken to cover the distence of 3 Km = 50*2/5 = 20 min = 1/3 hours
Remaining distance = 8 - 3 = 5 Km
Required speed = 5/1/3 = 15 Kmph

If X and Y are both positive two-digit integers and share no digits, and X > Y, what is the smallest possible value of X - Y?
Options:
(A) 0
(B) 1
(C) 2
(D) 3
(E) 9
Answer and stream of consciousness: (B)
Stream of consciousness: Answer = B = 1
20 - 19 = 30-29 = 40-39 = 50-49 = 1

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 and stream of consciousness: (E)
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.

Look at this series: 7, 10, 8, 11, 9, 12, ... What number should come next?
Options:
(A) 10
(B) 12
(C) 7
(D) 8
(E) 9
Answer and stream of consciousness:
(A)
Stream of consciousness: This is a simple alternating addition and subtraction series. In the first pattern, 3 is added; in the second, 2 is subtracted.
