In a particular course, only two grades are given all semester: the midterm exam, which counts for 25% of the semester grade, and the final exam, which counts for the remainder. Lindsey's semester grade was 88%. If the highest possible score on either exam is 100%, what is the lowest possible score O that Lindsey could have received on her midterm exam?	Select the correct option:  A) 52%  B) 64%  C) 72%  D) 76%  E) 80%

Solution: If the midterm counts for 25% of the total grade, then the final exam must count for the remaining 75%, meaning that in this weighted average problem the final is weighted 3 times as much as the midterm. Using the weighted average mapping strategy, then, and maximizing her final exam score so that you minimize her midterm score, you have:   100-------------88----------------------------x   And you know that the ratio is 3:1. Since the final exam score of 100 is weighted heavier, then the difference of 12 between 100 and 88 is the1part of the ratio, meaning that 3(12) is the 3 portion. That equals 36, so the midterm score (x) is 36 less than the weighted average of 88. 88 - 36 = 52, sothe correct answer is 52%.
Answer: A
In the Johnsons' monthly budget, the dollar amounts allocated to household expenses, food, and miscellaneous items are in the ratio 4:3:1, respectively. If the total amount allocated to these three categories is $1,800, what is the amount allocated to food?  Choose the correct option:
A) $900 B) $720 C) $675 D) $450 E) $225

Solution: To solve this question, it will be best to first express the given ratio using variable multipliers. Thus, we have:   Household Expenses : Food : Miscellaneous = 4x : 3x : x   Since we are told that the TOTAL amount allocated to these categories is $1,800 we can set up the equation:   4x + 3x + x = 1,800   8x = 1,800   x = 225   Thus, the total amount allocated to food is 3 x 225 = $675.   Answer $675.
Answer: C
A wheel has a diameter of x inches and a second wheel has a diameter of y inches. The first wheel covers a distance of d feet in 130 revolutions. How many revolutions does the second wheel make in covering d feet?
Choose the correct option
A) 65x+y
B) 130x/y
C) 130x+y
D) 100x-y
E) 130y/x

Solution: A wheel covers 2πr distance in one revolution. where r= diameter/2   First wheel covers d feet in 130 rev. => d= 130* 2π * (x/2)   Second wheel covers d feet in let's say P revolutions; => d = P* 2π * (y/2)   comparing both equations:-   => p= (130∗2π∗x/2)/(2π∗y/2)   => 130x/y   Answer :- 130x/y

In an election only two candidates contested. A candidate secured 70% of the valid votes and won by a majority of 172 votes. Find the total number of valid votes?  Options.
A) 430  B) 438  C) 436  D) 434  E) 422

Solution: Let the total number of valid votes be x.   70% of x = 70/100 * x = 7x/10   Number of votes secured by the other candidate = x - 7x/100 = 3x/10   Given, 7x/10 - 3x/10 = 172 => 4x/10 = 172   => 4x = 1720 => x = 430.   430nswer:430

150 friends liked.   Twitter : 42% of 300 friends liked my post, hence  0.42*300= 
 0.42*300 = 126
126 seeds germinated.   Thus (friends who liked my post) /(total)= (150 + 126)/(400 + 300) = 276/600 = 46% seeds germinated.   Answer: 46.0%.

The ratio of the present age of Sandy to that of Molly is 7:2. Sixteen years from now, the ratio of the ages of Sandy to Molly will be 5:2. What was Sandy's age 6 years ago?	Select: A) 66 B) 70 C) 74 D) 78 E) 82

Solution: Let the present age of Sandy be 7x years and that of Molly be 2x years.   (7x + 16) / (2x + 16) = 5 / 2   4x = 48   x = 12   Six years ago, Sandy's age was 7(12) - 6 = 78   The answer is 78.

In the game of Dubblefud, yellow chips, blue chips and green chips are each worth 2, 4 and 5 points respectively. In a certain selection of chips, the product of the point values of the chips is 16,000. If the number of blue chips in this selection equals the number of green chips, how many yellow chips are in the selection?
Pick one
A) 1 B) 2 C) 3 D) 4 E) 5

Solution: this is equivalent to :-   2x * 4y * 5z = 16000   y = z (given)   2x * 4y * 5y = 16000   2x * y^2 = 16000/20   2x * y^2 = 800   now from options given we will figure out which number will divide 800 and gives us a perfect square :-   which gives us x = 4 as   2* 4 * y^2 =800   y^2 = 100   y =10   Number of yellow chips = 4 hence 4
Answer: D
A man rides at the rate of 30km/hr. But stops 20minutes to change horses at the end of every 60th kilometer. How long will he take to go a distance of 180 kilometers?
Choose the correct choice from the following answers:
A) 5hr  B) 6hr 30min  C) 6hr 40min  D) 7hr 20min  E) 9hr

Solution: speed of man = 60km/hr   number of rests = (180/60)-1= 
(180/60)-1 = 2
2   time taken for the man= (180/30)+2*(20/60) = 6 hr 40 min   Answer is 6hr 40min
Answer: C
The sum of 3 hours 45 minutes and 3 hours 55 minutes is approximately what percent of a day?	Answers:  A) 35%  B) 34%  C) 33%  D) 32%  E) 31%

Solution: Since the question is asking for an approximate percentage   3:45+3:55 ~ 8 hours   % of day = 8*100/24 ~ 8*100/25= 
8*100/25 = 32
32%   Answer is 32%.
Answer: D
The last digit of 12^12+13^13–14^14×15^15 = Choose one: A) 0 B) 1 C) 5 D) 8 E) 9

Solution: 12^12+13^13–14^14∗15^15   =12^12+13^13–(14^14∗15^15)   Note that the answer would be -ve for this question   So, Just for the sake of last digit, I'm re-arranging the term as below   (14^14∗15^15)−(12^12+13^13)   (14^14∗15^15) >> As 4 & 5 are at the units place, the units place would be 0 of the product. No need of further calculation   12^12>> Cyclicity is 2, 4, 8, 6... units digit = 6   13^13 >> Cyclicity is 3, 9, 7, 1... units digit = 3   0 - (6+3)   = 0 - 9 = 1 at the units place   Answer = 1 = 1
Answer: B
Tom and Jerry are running on the same road towards each other. If Tom is running at a speed of 2.5 meters per second and Jerry is running 36% slower, how much time W will it take them to meet if the initial distance between the two is 50 meters and Tom started running 20 seconds before Jerry did?	Answers:
A) 2 minute and 12 seconds.
B) two minutes.
C) 44 seconds.
D) 20 seconds.
E) 12 seconds.

Solution: Tom is running alone for 20 seconds.   So he will cover a distance of  20*2.5= 
 20*2.5 = 50
50 m in 20 seconds=W   Basically, Jerry has not started yet , and Tom has covered the distance alone and met Jerry on the other side   20 seconds. is the answer

Q:Robert purchased $1000 worth of US saving bonds. If bonds are sold in $50 or $100 denominations only, which of the following CANNOT be the number of US saving bonds that Robert purchased? Choose the most appropriate option:
A) 10  B) 12  C) 17  D) 20  E) 30

Solution: I started off with looking at the answer choices... 10-12-17-20 are in a tight range, so my guess was to look and rule out the bigger numbers.   The total amount is $1000. So with 30 bonds, each $50 = $1500 , we already exceed the $1000 limit. Hence 30 is the answer.
