q: The number of people at Ovations Bar in the hour from 12 p.m. to 1 p.m. was 30% greater than the number of people there from 11 a.m. to 12 p.m. The number of the people at the bar from 11 a.m. to 12 p.m. was 20% less than the number there from 10 a.m. to 11 a.m. If 92 people were at the bar from 11 a.m. to 1 p.m., which of the following is the number of people in the bar from 10 a.m. to 11 a.m.?
Options:
(A) 10
(B) 20
(C) 30
(D) 40
(E) 50
a: Stream of consciousness: No of people from 10 - 11 is x
No of people from 11 - 12 is 4x/5
No of people from 12 to 1 is (13/10)(4x/5)
Given that 4x/5 + (13/10)(4x/5) = 92x/50 = 92
Then x = 50 The answer is (E).


question: 7528:5306::4673:?
Options:
(A) 2351
(B) 2451
(C) 2551
(D) 2651
(E) 2751
answer: Stream of consciousness: As there is a difference of 2222. 7528-2222 = 5306. so 4673-2222 = 2451 The answer is (B).

Options:
(A) 48
(B) 24
(C) 120
(D) 60
(E) None of these
a: Stream of consciousness: Reqd. number = 4! × 2! = 24 × 2 = 48 The answer is (A).


question: Which of the following numbers is divisible by 4?
Options:
(A) 27767
(B) 10224
(C) 26778
(D) 26679
(E) 26711
answer: Stream of consciousness: 10224. This is the only option with last two digits divisible by 4 The answer is (B).


q: A train 495 m long is running at a speed of 63 km/hr. In what time will it pass a bridge 240 m long?
Options:
(A) 39
(B) 40
(C) 41
(D) 42
(E) 43
a: Stream of consciousness: Speed = 63 * 5/18 = 35/2 m/sec
Total distance covered = 495 +240 = 735 m
Required time = 700 * 2/35 = 42 sec The answer is (D).


q: 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
a:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

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).
