question: A deer runs k miles in n hours. How many miles will it run in x hours at the same rate?
Options:
(A) knx
(B) kn
(C) kx2n
(D) kxn
(E) knx
answer: Stream of consciousness: Given Speed = k/n
To Find distance in x hours with same speed
Distance = speed * time
Distance = k/n*x = kx/n The answer is (D).

q: X can finish a work in 25 days. Y can finish the same work in 20 days. Y worked for 12 days and left the job. how many days does X alone need to finish the remaining work?
Options:
(A) 2
(B) 5
(C) 6
(D) 7
(E) 8
a: Stream of consciousness: Work done by X in 1 day = 1/25
Work done by Y in 1 day = 1/20
Work done by Y in 12 days = 12/20 = 3/5
Remaining work = 1 3/5 = 2/5
Number of days in which X can finish the remaining work = (2/5) / (1/20) = 8 The answer is (E).

question: How much is 80% of 40 is greater than 4/5 of 25?
Options:
(A) 12
(B) 27
(C) 18
(D) 12
(E) 81
answer: Stream of consciousness: (80/100) * 40 (4/5) * 25
32 - 20 = 12 The answer is (D).

q: A man rows his boat 70 km downstream and 45 km upstream, taking 2 1/2 hours each time. Find the speed of the stream?
Options:
(A) 1 kmph
(B) 6 kmph
(C) 5 kmph
(D) 8 kmph
(E) 7 kmph
a: Stream of consciousness: Speed downstream = d/t = 75/(2 1/2) = 28 kmph
Speed upstream = d/t = 45/(2 1/2) = 18 kmph
The speed of the stream = (28 - 18)/2 = 5 kmph The answer is (C).

question: In what time a sum of money double itself at 3% per annum simple interest?
Options:
(A) 33 1/4%
(B) 33 1/3%
(C) 33 7/3%
(D) 33 5/3%
(E) 33 1/7%
answer: Stream of consciousness: P = (P*3*R)/100
R = 33 1/3% The answer is (B).
