question: A woman begins bicycling with a pace of 10 kmph and she increases her pace every two hours by 2 kmph. She rests from bicycling 2 hours after her pace reaches her maximum speed of 14 kmph. She does a cool-down for the final 8 km at a pace of 2 kmph. How far in km did she bicycle?
Options:
(A) 96 km
(B) 100 km
(C) 106 km
(D) 116 km
(E) 126 km
answer: Stream of consciousness: Distance covered in first two hours = 10 2 = 20 km
Distance covered in next two hours = 12 2 = 24 km
Distance covered in next two hours = 14 2 = 48 km
Distance covered in first six hours
20 + 24 + 48 = 92 km
Remaining distance = 8 km
92 + 8 = 100 km The answer is (B).

q: Anil can do a work in 15 days while Sunil can do it in 25 days. How long will they take if both work together?
Options:
(A) 9 3/6
(B) 9 3/4
(C) 9 3/8
(D) 5 3/2
(E) 9 3/2
a: Stream of consciousness: 1/15 + 1/25 = 8/75
75/8 = 9 3/8 days The answer is (C).

question: Every year an amount increases by 1/8th of itself. How much will it be after two years if its present value is Rs.64000?
Options:
(A) 81000
(B) 22887
(C) 26877

Options:
(A) 2599980
(B) 235500
(C) 923580
(D) 765432
(E) 765434
a: Stream of consciousness: 10(11111)*4! - 10(1111)3! = 2599980 The answer is (A).

q: Of the 50 electronics components that a factory must
manufacture, 70 percent would be most e ciently manufactured
by Machine A and the remaining 30 percent would be most
e ciently manufactured by Machine B, though either machine
could manufacture any of the 50 components. If 36 percent of
the components were manufactured by Machine A and the
remainder were manufactured by Machine B, what is the
highest possible number of components that were
manufactured by the machine that would manufacture them
the most efficiently?
Options:
(A) 30
(B) 31
(C) 32
(D) 33
(E) 34
a:
Stream of consciousness: # components A and B could manufacture efficiently:
A: 50*70% = 35
B: 50*30% = 15
# components A and B effectively manufacture:
A: 50*36% = 18
B: 50*64% = 32
Max. # components efficiently manufactured:
18 (from A) and 15 (from B) = 33 The answer is (D).
