A furniture dealer purchased a desk for $150 and then set the selling price equal to the purchase price plus a markup that was 50% of the selling price. If the dealer sold the desk at the selling price, what was the amount of the dealer's gross profit from the purchase and the sale of the desk?	Choose the correct option.
A) 60%  B) 70%  C) 100%  D) 90%  E) 80%

Solution: Anyway, in this question, there is no discount but the mark up is given as 50% of the selling price. So it is not 50% of $150 but instead, 50% of Selling price which is obtained by adding mark up to $150.   So if selling price is S,   150 + 50% of S = S   S = 300   Profit = 150 which is calculated on cost price in % terms. So  150/150 * 100= 
 150/150 * 100 = 100
100% is profit.   100%

John is building a rectangular fence around a garden. The length will be 5 feet shorter than its width. If the total area of the garden is 176 square feet, what is the length of the diagonal (in feet)?	Choose the correct choice from the following.
A) Between 18 and 19
B) Between 19 and 20
C) Between 20 and 21
D) Between 21 and 22
E) Between 22 and 23

Solution: To solve this, we first need to set up an equation for the area of the garden. If x is the width, then we have   x(x - 5) = 176. By putting the equation in standard form, we get x^2-5x-176=0. By using the quadratic formula, we get roots of -11 and 16. We know that x is the width, and x-5 is the length, so by using the roots, we get 16 as the width (x), and 11 as the length (x-5).   Once we have this, we can use the Pythagorean Theorem to solve for the diagonal. Plugging in the length and width, we will get d^2=16^2+11^2   =256+121= 
256+121 = 377
377   The square root of 377 is less than 20, since 20^2= 400. Going down a number, we can compute 19^2 = 361 < 377. Therefore, the length of the diagonal must be between 19 and 20.   The correct answer is Between 19 and 20.

On a certain day, orangeade was made by mixing a certain amount of orange juice with an equal amount of water. On the next day, orangeade was made by mixing the same amount of orange juice with twice the amount of water. On both days, all the orangeade that was made was sold. If the revenue from selling the orangeade was the same for both days and if the orangeade was sold at $0.60 per glass on the first day, what was the price Q per glass on the second day?
Choose the correct answer:
A) $015
B) $0.20
C) $0.30
D) $0.40
E) $0.45

Solution: On the first day 1 unit of orange juice and 1 unit of water was used to make 2 units of orangeade;   On the second day 1 unit of orange juice and 2 units of water was used to make 3 units of orangeade;   So, the ratio of the amount of orangeade made on the first day to the amount of orangeade made on the second day is 2 to 3. Naturally the ratio of the # of glasses of orangeade made on the first day to the # of glasses of orangeade made on the second day is 2 to 3.   We are told thatthe revenue from selling the orangeade was the same for both daysso the revenue from 2 glasses on the first day equals to the revenue from 3 glasses on the second day.   Say the price of the glass of the orangeade on the second day was $x then 2*0.6=3*x --> x=$0.4.   Answer: $0.40.

The sequence of numbers a1, a2, a3, ..., an is defined by an = 1/n - 1/(n+2) for each integer n >= 1. What is the sum of the first 50 terms of this sequence? Choose the correct choice from the following options.
A) (1+1/2) – (1/51 +1/ 52)
B) (1/51 +1/ 52)
C) (1+1/2) +(1/51 +1/ 52)
D) (1+1/2) – 1/51
E) (1+1/2) – 1/52

Solution: The answer would most certainly be[A]. But the question needs a slight modification.n>=1, since the answer does consider a1 under the sum.   The sequence is :   a1 = 1-1/3   a2 = 1/2 - 1/4   a3 = 1/3 - 1/5....   We can observe that the third term in the sequence cancels the negative term in the first. A similar approach can be seen on all the terms and we would be left with 1 + 1/2 from a1 and a2 along with -1/52 and -1/51 from a50 and a49 term which could not be cancelled.
