January 25, 2014, fell on a Saturday. On which day of the week did January 25, 2016, fall? (Note: 2016 was a leap year.) Options
A) Sunday B) Monday C) Tuesday D) Wednesday E) Thursday

Solution: There are 365 days in a non-leap year, and 366 in a leap year.   365 / 7 = 52 remainder 1, so for every non-leap year the day of the week advances by 1.   January 25, 2014 = Saturday   January 25, 2015 = Sunday   January 25, 2016 = Monday   Even though 2016 is a leap year, with 366 days, the extra day does not come into play until February 29. Since the date range in question did not contain February 29, 2016, the day of the week only advances 1 day for 2016.   The answer is Monday.

If the sum of all consecutive integers from A to B (A<B), inclusive, is S and the average (arithmetic mean) of these integers is M, then, in terms of A, B, and S, what is the value of M?  Choose the correct choice from the following:  A) 2S/(A+B+1)  B) 2S/(A+B)  C) (B−A)/2  D) S/(B−A+1)  E) (B−A)/(2S)

Solution: Mean=sum of all the terms /number of terms   We already know the sum which is given as S.   We need the number of terms which needs to be calculated.   Since this is evenly placed set (set of consecutive numbers forms an AP with common difference of 1)   Number of terms in an AP is given by : Last term−first term common difference+1   Using this , we get the number of terms as : B - A + 1 (d = 1 in this case)   Hence the answer is: M=S/(B−A+1);   ANSWER:S/(B−A+1)

The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical A present and inversely proportional to the concentration of chemical B present. If the concentration of chemical B is increased by 100%, which of the following is closest to the percent change in the concentration of chemical A required to keep the reaction rate unchanged?	Answers.
A) 100% decrease B) 50% decrease C) 40% decrease D) 40% increase E) 50% increase

Solution: CA: Concentration A   CB: Concentration B   R: Reaction rate   Formula for reaction rate:   R = (CA^2) / CB   Thus if CB is increased by 100% >> means concentration doubles >> 2xCB   Thus, for R to remain the same (CA^2) also has to double.   >> 2 x (CA^2) >> to see what happens to CA, take the 2 into the bracket by taking its root   >> (SQRT 2 CA)^2   SQRT 2 is roughly 40% >> answer 40% increase

3/5 of all married couples have more than one child. 1/4 of all married couples have more than 3 children. What fraction of all married couples have 2 or 3 children?
Choose the most appropriate option
A) 1/5 B) B.1/4 C) 7/20 D) 3/5 E) It cannot be determined from the given information.

Solution: Plug in simple numbers. Take 100 couples for example.   3/5 of 100 couples have more than one child = 60 couples.   1/4 of 100 couples have more than 3 kids = 25 couples.   This implies that 25 couples are a subset of 60 couples and the complement of 60 couples within those 100 couples, which equals 40 couples have either one or no kids at all.   We need to find couples that have 2 or 3 kids, so essentially, it is  60 - 25= 
 60 - 25 = 35

On the xy co-ordinate plane, point C is (5,-2) and point D is (-1,1.5). The point on line segment CD that is twice as far from C as from D is:  Answers.
A) (1,-1)
B) (1,1)
C) (2,0.25)
D) (3,0.5)
E) (3,1)

Solution: We want the point on the line that is twice as far from C as it is from D. We can examine the x and y coordinates separately since they are independent.   *It should be noted that there are two solutions to this problem, one point between C and D, and another point with D in the middle of C and the point. We can quickly look at the answer choices and see that all the points are between C and D, therefore we can search for that point using the following method:   Taking the x-coordinate first, the distance between C and D is |(x-coordinate of C) - (x-coordinate of D)|= |5 - (-1)= 
5 - (-1) = 6
6   The x-coordinate that is twice as far from C as it is from D (and in between C and D) will be 4 units from C and 2 units from D. So the x coordinate of the point we're looking for is  5-4= 
 5-4 = 1
1, or  (-1)+2= 
 (-1)+2 = 1
1.   Now looking at the y-coordinate, we do the same thing. The distance between C and D is |(-2) - 2.5|= 4.5   The y-coordinate that is twice as far from C as it is from D (and in between C and D) will be 3 units from C and 1.5 units from D. So the y coordinate of the point we're looking for is  (-2)+3= 
 (-2)+3 = 1
1, or  2.5-1.5= 
 2.5-1.5 = 1
1.   So now we have our coordinates of the point on the line that is twice as far from C as it is from D: (3,1)   Answer: (3,1)
