q: The total price of a kilogram each of Shimla apples and Red Delicious apples is 250 rupees more than the total price of a kilogram each of Red Delicious apples and Fuji apples. Fuji apples is how much cheaper than Shimla apples?
Options:
(A) 250
(B) 125
(C) 500
(D) 100
(E) 80
a: Stream of consciousness: (Shimla + Red Delicious) - (Red Delicious + Fuji) = 250
Shimla - Fuji = 250 The answer is (A).

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: Find the number of zeroes in the expression 15*32*25*22*40*75*98*112*125
Options:
(A) 9
(B) 8
(C) 7
(D) 6
(E) 5
a: Stream of consciousness: Maximum power of 5 in the above expression can be calculated like this. Count all the powers of 5 in the above expression. So number of zeroes are 9. The answer is (A).

question: 85% of the population of a city is 85000. The total population of the city is?
Options:
(A) 95000
(B) 97500
(C) 100000
(D) 105000
(E) 102500
answer: Stream of consciousness: X * (85/100) = 85000
X = 1000 * 100
X = 100000 The answer is (C).

q: If the personal income tax rate is lowered from 46% to 32%, what is the differential savings for a tax payer having an annual income before tax to the tune of $36000?
Options:
(A) $3500
(B) $5040
(C) $3150
(D) $7000
(E) $10000
a: Stream of consciousness: Saving = (46-32)% of 36000 = 5040. The answer is (B).

q: The length of a rectangle is increased by 45% and its breadth is decreased by 20%. What is the effect on its area?
Options:
(A) 1288
(B) 1299
(C) 1000
(D) 10000
(E) 11600
a:
Stream of consciousness: 100 * 100 = 10000
145 * 80 = 11600 The answer is (E).
