question: 4000 was divided into two parts such a way that when first part was invested at 3% and the second at 5%, the whole annual interest from both the investments is Rs.144, how much was put at 3%?
Options:
(A) 3377
(B) 2678
(C) 2800
(D) 2786
(E) 1981
answer: Stream of consciousness: (x*3*1)/100 + [(4000 - x)*5*1]/100 = 144
3x/100 + 200 5x/100 = 144
2x/100 = 56 e x = 2800' The answer is (C).

q: An accurate clock shows 8 o'clock in the morning. Through how may degrees will the hour hand rotate when the clock shows 2 o'clock in the afternoon?
Options:
(A) 270
(B) 360
(C) 280
(D) 90
(E) 180
a: Stream of consciousness: Angle traced by the hour hand in 6 hours = (360/12 x 6) = 180. The answer is (E).

question: Two trains are moving at 50 kmph and 70 kmph in opposite directions. Their lengths are 150 m and 100 m respectively. The time they will take to pass each other completely is?
Options:
(A) 7 1/9
(B) 7 1/8
(C) 7 1/3
(D) 7 1/2
(E) 7 1/1
answer: Stream of consciousness: 70 + 50 = 120 * 5/18 = 100/3 mps
D = 150 + 100 = 250 m
T = 250 * 3/100 = 15/2 = 7 1/2 sec The answer is (D).

q: The radius of a cylinder is 2 r units and height is 3 r units. Find the curved surface?
Options:
(A) 27
(B) 16
(C) 12
(D) 18
(E) 11
a: Stream of consciousness: 2 * * 2r * 3r = 12 r2 The answer is (C).

question: If a man can cover 32 metres in one second, how many kilometres can he cover in 3 hours 45 minutes?
Options:
(A) 118 km
(B) 162 km
(C) 1767 km
(D) 432 km
(E) 177 km
answer: Stream of consciousness: 32 m/s = 32 * 18/5 kmph
3 hours 45 minutes = 3 3/4 hours = 15/4 hours
Distance = speed * time = 32 * 18/5 * 15/4 km = 432 km. The answer is (D).

question: A no.when divided by 125 gives a remainder 40, what remainder will be obtainedby dividingthe same no.15?
Options:
(A) 10
(B) 11
(C) 12
(D) 13
(E) 14
answer:
Stream of consciousness: 125 + 40 = 165/15 = 11 (Remainder) The answer is (B).
