q: 30 pens and 75 pencils were purchased for 750. If the average price of a pencil was 2.00, find the average price of a pen.
Options:
(A) 20
(B) 11
(C) 12
(D) 13
(E) 14
a: Stream of consciousness: Since average price of a pencil = 2
Price of 75 pencils = 150
Price of 30 pens = (750 150) = 600
Average price of a pen = 60060 = 20 The answer is (A).

question: A train 124 m long running at 68 kmph crosses a platform in 19 sec. What is the length of the platform?
Options:
(A) 338
(B) 234
(C) 240
(D) 881
(E) 271
answer: Stream of consciousness: D = 68 * 5/18 = 19 = 358 124 = 234 The answer is (B).

q: A train running at the speed of 60 km/hr crosses a pole in 9 sec. What is the length of the train?
Options:
(A) 120 m
(B) 180 m
(C) 324 m
(D) Cannot be determined
(E) None of these
a: Stream of consciousness: Speed = 60 * 5/18 = 50/3 m/sec
Length of the train = speed * time = 50/3 * 9 = 150 m The answer is (E).

question: From group of 15 cricket players a team of 11 players is to be chosen. How many ways this can be done?
Options:
(A) 3252
(B) 1365
(C) 5325
(D) 1432
(E) 1324
answer: Stream of consciousness: 11 players are to be chosen from 15 players. This can be done in 15C11 ways. ie) 15!/11!x4! = 1365 ways. Ans: The answer is (B).

question: Two trains are traveling on parallel tracks in the same direction. The faster train travels at 130 miles per hour, while the slower train travels at 100 miles per hour. At 2 o'clock the faster train is 15 miles behind the slower one. How far apart are the two trains at 5 o'clock?
Options:
(A) 60 miles
(B) 80 miles
(C) 75 miles
(D) 120 miles
(E) 400 miles
answer:
Stream of consciousness: Answer = C. 75 miles
Relational speed = 130 - 100 = 30 miles per hour
In 3 hours, difference = 30 * 3 = 90 miles
Fast train trailing 15 miles, so effective difference = 90 - 15 = 75 miles The answer is (C).
