question: Find 95 98
Options:
(A) 93/198
(B) 93/12
(C) 93/13
(D) 93/10
(E) 93/11
answer: Stream of consciousness: Here both numbers are less than 100. So they are deficient of - 5 and - 2 compared with 100. So The answer is (D).

q: A man pointing to a photo says "The lady in the photograph is my nephew's maternal grandmother". How is the lady in the photograph related to the man's sister who has no other sister ?
Options:
(A) Cousin
(B) Sister-in-law
(C) Mother
(D) Mother-in-law
(E) None of these
a: Stream of consciousness: Since the man is referring to his nephew, the nephew's parent has to be a sibling to the man. Now the last part says that the man's sister has no other sister and hence the brother-sister relationship is established between the man and his nephew's mother. Now the lady in the picture is the grandmother of the nephew and hence she is the mother of the man's sister. The answer is (C).

question: In the x-y plane, point (x, y) is a lattice point if both x and y are integers. Circle C has a center at (-2, -2) and a diameter of 8. Some points, such as the center (-2, -2), are inside the circle, but a point such as (-2, 2) is on the circle but not in the circle. How many lattice points are in circle C?
Options:
(A) 40
(B) 10
(C) 73
(D) 60
(E) 63
answer: Stream of consciousness: The lattice points that are in the circle that lie on the perspective axes is as follows: since the diameter is 8, 9 points lie on the horizontal axis (8 + center), but the end points are not in the circle, so 9 - 2 (the same for the vertical axis, but don't count center again), 7 - 1. The lattice points in the circle and not on the horizontal and vertical axes is as follows: lattice points can be found at 45, 45/2 and 30 degrees of axes (30 and 45/2 degrees from horizontal and vertical axes), so same numbers as before, but don't count center again. So, 13 + 5 * 12 = 73
There are a total of 73 lattice points in the circle. The answer is (C).

q: 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) 1:5
(C) 1:9
(D) 1:3
(E) 1:1
a: 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).

question: Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 1 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. The capacity of the tank is?
Options:
(A) 40 gallons
(B) 100 gallons
(C) 120 gallons
(D) 180 gallons
(E) 130 gallons
answer: Stream of consciousness: Work done by the waste pipe in 1 minute = 1/15 - (1/20 + 1/24) = - 1/40
Volume of 1/40 part = 1 gallonsVolume of whole = 1 * 40 = 40 gallons. The answer is (A).

question: The radius of a cone is 4 m, height 5 m. Find the curved surface area?
Options:
(A) 1
(B) 3
(C) 5
(D) 7
(E) 9
answer:
Stream of consciousness: Cone curved surface area = rl = 22/7 4 5 = 440/7 = 62 6/7
Slant height (l) = r(power2)+h(power2) = 16+9 = 25 = 5 The answer is (C).
