Because he’s taxed by his home planet, Mork pays a tax rate of 40% on his income, while Mindy pays a rate of only 20% on hers. If Mindy earned 4 times as much as Mork did, what was their combined tax rate? Choose the correct choice from the following answers:
A) 22.5%  B) 24%  C) 30%  D) 33%  E) 20%

Solution: Say Morks income is - 100   So tax paid will be 40   Say Mindys income is 4*100= 
4*100 = 400
400   So tax paid is 20% * 400= 80   Total tax paid = 40+80= 
40+80 = 120
120.   Combined tax % will be 120/100+400= 24%

Answer: B
The GDP of a country is $13.8 billion, and the total production of one of its industries is $3.3 billion. If the GDP were to grow by 5% per year in the future, which of the following would be the MINIMUM required annual growth in this industry that would it represent more than half of the GDP in ten years?
Choose the correct choice:
A) 10%
B) 15%
C) 20%
D) 25%
E) 35%

Solution: GDP in 10 years with this rate would be - 13.8 (1+0.05)^10   Half of the above value - 6.9 (1.05)^10   Industry's annual growth (say x is the rate of growth of the industry annually) = 3.3 (1+(x/100))^10   Now, the minimum of above value has to be greater than the half of the value of GDP.   3.3 (1+(x/100))^10 > 6.9 (1.05)^10   ((1+(x/100))/1.05)^10 > 2 (approx)   Minimum value of x to satisfy this equation is 15   Hence 15%

In the standard formulation of a flavored drink the ratio by volume of flavoring to corn syrup to water is 1 : 12 : 30. In the sport formulation, the ratio of flavoring to corn syrup is three times as great as in the standard formulation, and the ratio of flavoring to water is half that of the standard formulation. If a large bottle of the sport formulation contains 1 ounces of corn syrup, how many ounces of water does it contain? Options
A) 15
B) 30
C) 45
D) 60
E) 90

Solution: Standard:   Fl: Corn S: Water = 1:12:30   Sport:   Fl: Corn S: Water = 3:12:180   This simplifies to 1:4:60   If the large bottle has a capacity of x ounces, then   4x / 65 = 1.   So, x =65 / 4 ounces.   Water = (60 / 65) * (65 / 4)= 
(60 / 65) * (65 / 4) = 15
15 ounces.   15ns 15

Obra drove 180π meters along a circular track. If the area enclosed by the circular track on which she drove is 57,600π square meters, what percentage of the circular track did Obra drive?  Select:
A) 37.5%	B) 12.5%	C) 18.75%	D) 25%	E) 33.3%

Solution: area enclosed by the circular track on which she drove is 57,600π square meters   So, π(r^2) = 57,600π ---> (r^2)=57,600 ---> r=240   Circumference of the circular track = 2πr = 480π   Therefore, part of circumference covered = 180π/480π =37.5%   Hence, answer is 37.5%.

Find the area of a rhombus one side of which measures 20 cm and one diagonal is 28 cm.
Choices:
A) 200cm2  B) 300cm2  C) 400cm2  D) 448cm2  E) 100cm2

Solution: Explanation: Let other diagonal = 2x cm.   Since diagonals of a rhombus bisect each other at right angles, we have:   (20)2 = (12)2 + (x)2 =>x =√(20)2 – (12)2= √256= 16 cm. _I   So, other diagonal = 32 cm.   Area of rhombus = (1/2) x (Product of diagonals) =(1/2× 28 x 32) cm2 = 448 cm2   Answer: Option 448cm2

Two identical machines have the ability to produce both nuts and bolts. However, it takes 1 second to produce a bolt but 2 seconds to produce a nut. What is the fastest the two machines, working together, can produce 1,600 nuts and 1,600 bolts? Pick:  A) 1,250 seconds  B) 1,500 seconds  C) 1,750 seconds  D) 2,400 seconds  E) 3,000 seconds

Solution: I used the Rate formula (R=\frac{1}{T})   Rate of 1st machine = Rate of making 1 bolt + Rate of making 1 nut = 1 + \frac{1}{2}   Rate of 1st machine = Rate of 2nd machine   After this I got lost.   Please can you help how to approach using algebra?   I wouldn't complicate:   1 machine needs 1,600*1 seconds to produce 1,600 bolts, so 2 need half of that, so 1,600/2 seconds.=800   1 machine needs 1,600*2 seconds to produce 1,600 nuts, so 2 need half of that, so 1,600*2/2 seconds.=1600   total = 2400   2,400 seconds

Which of the following options is the possible total number of people in a hall given that the number of people is a multiple of both 8 and 14.?  Choose one:  A) 64  B) 72  C) 56  D) 80  E) 88

Solution: the number of people are a multiple of both 8 and 14, so it must be divisible by 8 and 14.   using the elimination method look for a number that is both divisible by 8 and 14,   of all the options only 56 is divisible by 8 and 14.   [ 56/8=1 and   56/14=

Jill works as a waitress at the local diner where she earns an hourly wage of $4.00 per hour and a standard tip rate of 15% of the cost of the orders she serves. If she worked two 8-hour shifts this week and averaged $40 in orders per hour, how much did Jill earn this week?	Choose the correct choice from the following options.
A) 280	B) 300	C) 160	D) 350	E) 400

Solution: Jill earns 4 dollars/hour and the hourly tip is (3/20)*40.   Jill thus earns 4*8+8*2*3 per day(or 4(8)+6(8)=10(8)=80).   Jill has worked for 2 days -> 80*2=160.   This matches answer choice 160.

James took a 3-hour bike ride. In the second hour he travlled 18 miles, which was 20 percent farther than he traveled the first hour. If he traveled 25 percent farther in the third hour than he did in the second hour, how many miles did jose travel during the entire ride? Select:  A) 54.0  B) 54.9  C) 55.5  D) 57.0  E) 63.0

Solution: Let the distance travelled in the first hour be x. Thus, 1.2x = 18 , x = 15. Now, the distance travelled in the 3rd hour = 18+1/4∗18= The only option ending with a 0.5 in the decimal place is C.   ANSWER:55.5
Answer: C
Donovan and Michael are racing around a circular 600-meter track. If Donovan runs each lap in 45 seconds and Michael runs each lap in 40 seconds, how many laps will Michael have to complete in order to pass Donovan, assuming they start at the same time?  Choices:	A) 8	B) 7	C) 9	D) 6	E) 5

Solution: One way of approaching this question is by Relative speed method   1. Speed/ Rate of Donovan = Distance/ time => 600/45 =>40/3   2. Speed/ Rate of Michael = Distance/ time => 600/40= 
600/40 = 15
> 15   Relative Speed between them= 15 - 40/3 => 5/3 (We subtract the Rates if moving in the same direction and add the rates if moving in the opposite direction)   In order to pass Donovan-   Distance to be covered = 600, Relative Rate = 5/3   Total Time taken by Micheal to surpass Donovan = Distance / rate => 600*3/5= 
600*3/5 = 360
> 360   No. of laps taken by Michael= Total time / Michael's rate => 360/40= 
360/40 = 9
> 9   Hence correct answer is 9 Laps.   9
