Options:
(A) 3484
(B) 3467
(C) 3567
(D) 4567
(E) 5184
a: Stream of consciousness: Given Exp. = (12)3 x 64 = (12)3 x 64 = (12)2 x 62 = (72)2 = 5184

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).

(B) 13678
(C) 23456
(D) 56789
(E) 79746
a: Stream of consciousness: 45789+ 34567 = 610+ ?
45789+ 34567 610 = 79746 The answer is (E).

q: A and B can do a work in 2 days, B and C in 6 days and C and A in 8 days. In how many days will the work be completed, if all three of them work together?
Options:
(A) 12/28
(B) 48/19
(C) 16/48
(D) 18/48
(E) 12/64
a:
Stream of consciousness: One day work of A and B = 1/2
One day work of B and C = 1/6
One day work of C and A = 1/8
2(A + B + C) = 1/2 + 1/6 + 1/8
2(A + B + C) = 19/24
(A + B + C) = 19/48
Number of days required = 48/19 days. The answer is (B).
