question: If 10 men can reap 120 acres of land in 15 days, how many acres of land can 20 men reap in 30 days?
Options:
(A) 120
(B) 240
(C) 360
(D) 1200
(E) 480
answer: Stream of consciousness: 10 men 120 acres 15 days
20 men ? 30 days
120 * 20/10 * 30/15
120 *2 * 2
120 * 4 = 480 The answer is (E).

q: A motorcyclist goes from Bombay to Delhi, a distance of 200 kms at an average of 50 kmph speed. Another man starts from Bombay by car 2 hours after the first, and reaches Delhi hour earlier. What is the ratio of the speed of the motorcycle and the car?
Options:
(A) 1:2
(B) 1:7
(C) 1:9
(D) 1:4
(E) 1:1
a: Stream of consciousness: T = 200/50 = 4 h
T = 4 - 3 = 1
Time Ratio = 4:1
Speed Ratio = 1:4 The answer is (D).

question: A train running at the speed of 30 km/hr crosses a pole in 9 sec. What is the length of the train?
Options:
(A) 75 m
(B) 180 m
(C) 324 m
(D) Cannot be determined
(E) None of these
answer: Stream of consciousness: Speed = 30 * 5/18 = 25/3 m/sec
Length of the train = speed * time = 25/3 * 9 = 75 m The answer is (A).

q: Three pipes A, B and C can fill a tank from empty to full in 30 minutes, 20 minutes and 10 minutes respectively. When the tank is empty, all the three pipes are opened. A, B and C discharge chemical solutions P, Q and R respectively. What is the proportion of solution Q in the liquid in the tank after 3 minutes?
Options:
(A) 1/11
(B) 2/11
(C) 3/11
(D) 4/11
(E) 5/11
a: Stream of consciousness: Part filled by (A + B + C) in 3 minutes = 3(1/30 + 1/20 + 1/10) = 11/20
Part filled by B in 3 minutes = 3/20
Required ratio = 3/20 * 20/11 = 3/11 The answer is (C).

question: Find the product of the localvalue and absolutevalue of 4 in 20468?
Options:
(A) 1000
(B) 1100
(C) 1200
(D) 1300
(E) 1600
answer: Stream of consciousness: Local value of 4 = 4 x 100 = 400
Place value of 4 = 4
There fore = 4 x 400 = 1600 The answer is (E).

question: A motorcyclist goes from Bombay to Pune, a distance of 192 kms at an average of 32 kmph speed. Another man starts from Bombay by car 2 hours after the first, and reaches Pune hour earlier. What is the ratio of the speed of the motorcycle and the car?
Options:
(A) 1:2
(B) 1:0
(C) 1:87
(D) 1:6
(E) 1:1
answer:
Stream of consciousness: T = 192/32 = 6 h
T = 6 - 3 = 3
Time Ratio = 6:3 = 2:1
Speed Ratio = 1:2 The answer is (A).
