Options:
(A) 18
(B) 99
(C) 22
(D) 26
(E) 71

question: The ratio of males and females in a city is 7 : 8 and the percentage of children among males and females is 25% and 20% respectively. If the number of adult females in the city is 156800 what is the total population?
Options:
(A) 245000
(B) 367500
(C) 196000
(D) 171500
(E) None of these
answer: Stream of consciousness: Number of females = 156800 10080 = 196000
\ Number of males = 78 196000 = 171500
\ Total population = 196000 + 171500 = 367500 The answer is (B).

q: A family pays $800 per year for an insurance plan that pays 85 percent of the first $1,000 in expenses and 100 percent of all medical expenses thereafter. In any given year, the total amount paid by the family will equal the amount paid by the plan when the family's medical expenses total.
Options:
(A) $1,100
(B) $1,200
(C) $1,400
(D) $1,800
(E) $2,200
a: Stream of consciousness: Upfront payment for insurance plan = 800$
Family needs to pay 15 % of first 1000 $ in expense = 150$
Total amount paid by family when medical expenses are equal to or greater than 1000 $ = 800 + 150 = 950 $
Total amount paid by insurance plan for first 1000 $ = 800 $
Total amount paid by family will equal amount paid by plan when medical expense = 1100 $
(Since insurance plan will pay 100% of amount that exceeds 950$ ) The answer is (A).

question: Eddy and Freddy start simultaneously from city A and they travel to City B and City C respectively. Eddy takes 3 hours and Freddy takes 4 hours to complete the journey. If the distance between City A and City B is 450 kms and City A and City C is 300 kms. What is the ratio of their average speed of travel? (Eddy: Freddy)
Options:
(A) 8/3
(B) 2
(C) 8/5
(D) 5/8
(E) 5/3
answer: Stream of consciousness: Distance traveled by Eddy = 450 km
Time taken by Eddy = 3 hours
Average speed of Eddy = 450/3 = 150 km/hour
Distance traveled by Freddy = 300 km
Time taken by Freddy = 4 hours
Average speed of Freddy = 300/4 = 75 km/hour
Ratio of average speed of Eddy to Freddy = 150/75 = 2 The answer is (B).

q: A = 10% of x, B = 10% of y, C = 10% of x + 10% of y. On the basis of the above equalities, what is true in the following?
Options:
(A) A is equal to B
(B) A is greater than B
(C) B is greater than A
(D) Relation cannot be established between A and B
(E) None of these
a: Stream of consciousness: The given information gives no indication regarding the comparison of x and y. The answer is (D).

q: The average of seven numbers is 18. The average of first three numbers is 12 and the average of last three numbers is 19. What is the middle number?
Options:
(A) 25
(B) 27
(C) 29
(D) 33
(E) 34
a:
Stream of consciousness: The total of seven numbers = 7X18 = 126
The total of first 3 and last 3 numbers is = 3 X 12+3 X 19 = 99
So, the middle number is (126 - 93 ) = 33 The answer is (D).
