Tom found a box of 220 baseball cards. Being a thoughtful older brother, he wanted to save at least 20 percent of the cards for himself and split the remaining cards evenly among his 4 younger brothers. What is the lowest possible number of cards that Tom can save for himself that will also allow each of his 4 younger brothers to get an equal number of cards?  Choose the correct answer
A) 110 B) 112 C) 116 D) 118 E) 120

Solution: This question can be easily solved by looking at the options.   Assuming number of cards to be x   We need to find the option for which (1/4)*(x/5) is an integer   Or x/20 is an integer.   Hence we need the lowest multiple of 20 from the given options.   Let us start from the lowest value:   Option A: 110. This is not a multiple of 20   Option E: 120 = 20*6. This is a multiple of 20. Hence the correct answer.   Correct Option: 120

Jake bought oranges at the supermarket for Y dollars an orange and sugar for M dollars per kilogram.
Then, he made lemonade using P oranges and Q kgs of sugar per liter and he sold Z liters of lemonade for X dollars per liter.
How much money has he made after selling all the lemonade?  Select: A) ZX(PY+QM) B) ZPM-ZQY C) XZ-PYZ-QMZ D) XZ-(MQ-YP) E) XQ-PY+ZM

Solution: First, the cost of the lemonade per liter= PY+QM dollars   Since Jake sold Z liters of lemonade, the cost price= Z(PY+QM) dollars   The selling price=ZX dollars   Profit=ZX-Z(PY+QM)   =(X-PY-QM)Z   The answer is XZ-PYZ-QMZ!!

This year, MBB Consulting fired 7% of its employees and left remaining employee salaries unchanged. Sally, a first-year post-MBA consultant, noticed that that the average (arithmetic mean) of employee salaries at MBB was 10% more after the employee headcount reduction than before. The total salary pool allocated to employees after headcount reduction is what percent of that before the headcount reduction?  Choose one.
A) 98.5%  B) 100.0%  C) 102.3%  D) 104.5%  E) 105.0%

Solution: 100 employees getting 1000$ avg, so total salary for 100 ppl = 100000   7% reduction in employees lead to 93 employees and a salary increase of 10% of previous avg salary   Thus the new avg salary is = 10%(1000)+1000 = 1100   so total salary of 93 employees is   93*1100= 
  93*1100 = 102_300
102300   Now the new salary is more than previous salary by x%. x= (102300/100000)*100= 
(102300/100000)*100 = 1_023/10 = around 102.3
102.3%   So the Answer is 102.3%

A) 15% B) 16% C) 14.5% D) 15.54% E) None of these

Solution: Explanation:   The resultant profit = 1.06 * 1.09= 
1.06 * 1.09 = 1.1554
1.1554= 15.54%   Alternatively, the resultant profit = [x + y + xy/100]   = 6 + 9 + (6*9)/100   = 15 + 0.54= 
15 + 0.54 = 15.54

Last week Vartan spent 15 percent of his wages on recreation. This week, his wages are 10 percent less than last weekʼs wages and he spent 30 percent of his wages on recreation. The amount he spends on recreation this week is what percent of the amount he spent on recreation last week?
Choose the most appropriate option:
A) 100% B) 160% C) 180% D) 200% E) 220%

Solution: Say Vartan's wages last week were $100, so he spent  0.15*100= 
 0.15*100 = 15
$15 on recreation;   This week's wages is 0.9*100= 
0.9*100 = 90
$90, so he spends   0.3*90= 
  0.3*90 = 27
$27 on recreation;   27/15= 
27/15 = 9/5 = around 1.8
1.8, hence the amount he spends on recreation this week is 180% of the amount he spent on recreation last week:   15*1.8= 
  15*1.8 = 27
27.   Answer: 180%.

Maria drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 9 hours. When Maria drove home, there was no traffic and the trip only took 4 hours. If her average rate was 40 miles per hour faster on the trip home, how far away does Maria live from the mountains?  Choose the correct choice
A) 787 miles	B) 772 miles	C) 287 miles	D) 979 miles	E) 288 miles

Solution: Explanation:   Time taken for trip from home to mountains = 9 h   Time taken for trip from mountains to home = 4 h   Let distance from home to mountains = x miles   let avg speed from home to mountains = y miles/h   Given avg speed on the trip home is 40 m/h faster than speed from home to mountains = y + 40 m/h   ⇒ (x/9) = y and (x/4) = y + 40   by solving this, we get y = 32 m/h and the distance x=32 × 9 = 288 miles.   Answer:288 miles

Ramesh spends 20% of his monthly salary on food, 10% of the remaining on conveyance and clothes and saves 75% of the remaining amount. If his monthly salary is Rs.20,000, how much money does he save every month ?  Select the correct option:
A) Rs.2645
B) Rs.7945
C) Rs.3694
D) Rs. 10080
E) Rs.1589

Solution: Explanation:   Ramesh's monthly income = Rs.20,000   He spends 20% on food.   The total money spent on food = 20/100 * 20000 = Rs. 4000   Now, his monthly remaining income = Rs.20000 – Rs.4000 = Rs. 16000   Out of Rs. 16000, he spends 10% on conveyance and clothes.   The total money spent on conveyance and clothes = 10/100 * 16000 = Rs. 1600   Now, his monthly remaining income = Rs.16000 – Rs.1600 = Rs. 14400   Out of Rs. 14400, he saves 70%.   Amount saved = 70/100 * 14400 = Rs. 10080   ANSWER:Rs. 10080

Answer: A
Set A is {1, 3, 5, 7, 9}
Set B is {10, 12, 14, 16, 18}
For the sets of numbers above, which of the following is true?
I. The mean of Set B is greater than the mean of Set A.
II. The median of Set B is greater than the median of Set A.
III. The standard deviation of Set B is greater than the standard deviation of Set A.	Choose one
A) I only
B) I and II only
C) I and III only
D) II and III only
E) I, II, and III

Solution: The mean and median of Set A is 5.   The mean and median of Set B is 14.   Thus statements I and II are both true.   The standard deviation is related to the distance from the mean.
