q: At a supermarket, a variety of cookies was priced at 75 cents per 100 grams. Subsequently, the price was revised to 40 cents for 30 grams of the same cookies. By approximately what percent did the ratio of price to weight increase from the initial price of 75 cents per pound?
Options:
(A) 65
(B) 78
(C) 44
(D) 18
(E) 36
a: Stream of consciousness: Initial price/weight ratio = 75 / 100 = 225/300
Revised price/weight ratio = 40 / 30 = 400/300 The answer is (B).

question: Find the largest 5 digit number which is exactly divisible by 88?
Options:
(A) 98765
(B) 98907
(C) 99944
(D) 99954
(E) 99968
answer: Stream of consciousness: Largest 5 digit number is 99999
After doing 99999 88 we get remainder 31
Hence largest 5 digit number exactly divisible by 88 = 99999 - 31 = 99968 The answer is (E).

q: The average age of A, B and C is 27 years. If the average age of A and C is 29 years, what is the age of B in years ?
Options:
(A) 19
(B) 35
(C) 20
(D) 32
(E) 23
a: Stream of consciousness: Age of B = Age of (A + B + C) Age of (A + C) = 27 3 29 2 = 81 58 = 23 years The answer is (E).

question: There are seven thieves. They stole diamonds from a diamond merchant and ran away. While running, night sets in and they decide to rest in the jungle.
When everybody was sleeping, two of them woke up and decided to divide the diamonds equally among themselves. But when they divided the diamonds equally, one diamond is left.
So they woke up the 3rd thief and tried to divide the diamonds equally again but still one diamond was left. Then they woke up the 4th thief to divide the diamonds equally again, and again one diamond was left. This happened with the 5th and 6th thief one diamond was still left.
Finally, they woke up the 7th thief and this time the diamonds were divided equally.
How many diamonds did they steal in total?
Options:
(A) 2397
(B) 2401
(C) 2411
(D) 2423
(E) None of the above
answer: Stream of consciousness: We need a number that is a multiple of 7 that will give a remainder of 1 when divided by 2, 3, 4, 5, and 6. The least common multiple of these numbers is 60. So, we need a multiple of 7 that is 1 greater than a multiple of 60. The answer is (B).

q: Rs.500 amounts to Rs.620 in 2 years at simple interest. If the interest is increased by 2%, it would amount to how much?
Options:
(A) 120
(B) 25
(C) 614
(D) 530
(E) 210
a: Stream of consciousness: (500*3*2)/100 = 30
500+ 30 = 530 The answer is (D).

q: Suppose you have three identical prisms with congruent equilateral triangles as the end-polygons. Suppose you attach them by the rectangular faces so they are perfectly aligned. There will be some large faces created by two or more co-planar faces of the individual prisms: count each such large face as one. Given that, how many faces does the resultant solid have
Options:
(A) 4
(B) 6
