Options:
(A) 8500
(B) 3500
(C) 4500
(D) 5000

question: A motorcyclist goes from Bombay to Pune, a distance of 256 kms at an average of 32 kmph speed. Another man starts from Bombay by car 2 ½ hours after the first, and reaches Pune ½ hour earlier. What is the ratio of the speed of the motorcycle and the car?
Options:
(A) 1:2
(B) 1:5
(C) 1:4
(D) 1:1
(E) 5:8
answer: Stream of consciousness: T = 256/32 = 8 h
T = 8 - 3 = 5
Time Ratio = 8:5
Speed Ratio = 5:8 The answer is (E).


q: If the two hands in a clock are 3 minutes divisions apart,then the angle between them is
Options:
(A) 3°
(B) 18°
(C) 24°
(D) 60°
(E) None of these
a: Stream of consciousness: In a clock, each minute makes 6°
∴ 3 minutes will make 6 × 3 = 18° The answer is (B).


question: A goods train runs at the speed of 72 km/hr and crosses a 250 m long platform in 26 sec. What is the length of the goods train?
Options:
(A) 49 sec
(B) 50 sec
(C) 48 second
(D) 43 sec
(E) 32 sec
answer: Stream of consciousness: D = 540 + 180 = 720
S = 54 * 5/18 = 15 mps
T = 720/15 = 48 se The answer is (C).


q: The speed of a boat in still water is 80kmph and the speed of the current is 20kmph. Find the speed downstream and upstream?
Options:
(A) kmph
(B) kmph
(C) kmph
(D) kmph
(E) kmph
a: Stream of consciousness: Speed downstream = 80 + 20 = 100 kmph
Speed upstream = 80 - 20 = 60 kmph The answer is (D).


q: If athul rows 16 km upstream and 24 km down steam taking 4 hours each, then the speed of the stream
Options:
(A) 1kmph
(B) 2 kmph
(C) 1.5 kmph
(D) 12 kmph
(E) 15 kmph
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: Speed upstream = 16/4 = 4 kmph
Speed down stream = 24/4 = 6 kmph
Speed of stream = ½ (6-4) = 1 kmph The answer is (A).
