Options:
(A) 1/ 225
(B) 1 / 30
(C) 1 /15
(D) 2 / 15
(E) 4 /15
a: Stream of consciousness: Q 1/15 + (14/15) * 1/14 = 2/15 The answer is (D).

question: Maxwell leaves his home and walks toward Brad's house at the same time that Brad leaves his home and runs toward Maxwell's house. If the distance between their homes is 50 kilometers, Maxwell's walking speed is 4 km/h, and Brad's running speed is 6 km/h. What is the distance traveled by Maxwell when they meet in the middle?
Options:
(A) 16
(B) 18
(C) 20
(D) 24
(E) 30
answer: Stream of consciousness: Distance between Maxwell's and Brad's home = 50 km
Maxwell's speed = 4 km/h
Brad's speed = 6 km/h
Relative speed of approach = 10 km/h
Time = 50/ 10 = 5 hours
Distance traveled by Maxwell when they meet in the middle = 4*5 = 20 km The answer is (C).

q: Two trains are moving at 50 kmph and 70 kmph in opposite directions. Their lengths are 150 m and 100 m respectively. The time they will take to pass each other completely is?
Options:
(A) 7 1/2 sec
(B) 2 sec
(C) 3 sec
(D) 5 sec
(E) 7 sec
a: Stream of consciousness: 70 + 50 = 120 * 5/18 = 100/3 mps
D = 150 + 100 = 250 m
T = 250 * 3/100 = 15/2 = 7 sec The answer is (A).

question: How much is 80% of 40 is greater than 4/5 of 20?
Options:
(A) 12
(B) 27
(C) 18
(D) 16
(E) 81
answer: Stream of consciousness: (80/100) * 40 (4/5) * 20
32 - 16 = 16 The answer is (D).

q: A train 260 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?
Options:
(A) 40
(B) 32
(C) 26
(D) 21
(E) 14
a: Stream of consciousness: Speed = 45 * 5/18 = 25/2 m/sec
Total distance covered = 260 + 140 = 400 m
Required time = 400 * 2/25 = 32 sec The answer is (B).

q: In how many different ways can the letters of the word 'PREPTY' be arranged?
Options:
(A) 280
(B) 290
(C) 300
(D) 340
(E) 360
a:
Stream of consciousness: Number of ways = 61/21 6X5X4X3X2X1 - 360 The answer is (E).
