#### If the average (arithmetic mean) of \(x, y\) and \(15\) is \(9,\) and the average of \(x, 2y\) and \(2\) is \(7,\) then

###### Problem Solving

##### Re: If the average (arithmetic mean) of \(x, y\) and \(15\) is \(9,\) and the average of \(x, 2y\) and \(2\) is \(7,\) t

Average of x,y & 15 is 9

i.e (x+y+15)/3 = 9

or x+y=12

Also, average of x,2y & 2 is 7

i.e (x+2y+2)/3 = 7

or x+2y = 19

Subtracting 1st equation from 2nd equation,

we get y = 7

Option C

##### Re: If \(8^c\cdot \sqrt8=\dfrac{8^a}{8^b}\) then \(a = ?\)

\(8^c\) . \(\sqrt{8}\) = \(8^{\left(c+\frac{1}{\left(2\right)}\right)}\)

Likewise, \(8^a\) / \(8^b\) = \(8^{a-b}\)

Thus, c+1/2=a-b

or a = b+c+1/2

Option E

##### Re: Arithmetic

Let the 3 consecutive integers be n, n+1 and n+2

Given, n+(n+1)+(n+2)=k

or 3n+3=k

or 3(n+1)=k

i.e k is thus a multiple of 3.

From the options given, only 201 is a multiple of 3.

Answer C.

##### Re: If \(9^{2x+5}=27^{3x-10},\) then \(x =\)

\(9^{2x+5}\) = \(3^{2\left(2x+5\right)}\)

= \(3^{4x+10}\)

Likewise,

\(27^{3x-10}\) = \(3^{3\left(3x-10\right)}\)

= \(3^{9x-30}\)

Equating the powers together;

4x+10 = 9x-30

i.e 5x=40

or x=8

Answer C

##### Re: \(x\) is between

Right angled triangle,

so \(x^2\) + 10 = \(\left(2\sqrt{\left(15\right)}\right)^2\)

Solving for x:

\(x^2\) =50

or x= \(\sqrt{50}\)

Thus, answer is Option D - between 7 & 8

##### Re: If \(5x - 3y = 7\) and \(2y - 4x = 3,\) then \(2x - 2y =\)

5x-3y=7

2y-4x=3

Add both the equations:

x-y=10

so 2(x-y)=2(10)

i.e 2x-2y=20

Answer E

###### Problem Solving

##### Re: The integer k, l, and and m are consecutive even integers between 23 and 33. Which of the following...

The arithmetic mean of 3 consecutive even integers would be the middle even integer. That rules out both options B and C. For option A to be the answer, the numbers need to be 22,24 & 26, but 22 is outside the range provided. For option E to be the answer, the numbers need to be 30,32 & 34 but 34 is...

#### If a rectangle has perimeter of 20 and a diagonal with length 9, what is the area of the rectangle?

###### Problem Solving

##### Re: If a rectangle has perimeter of 20 and a diagonal with length 9, what is the area of the rectangle?

Let l be the length and b the breadth Perimeter is 20 So, 2(l+b)=20 i.e l+b=10 Squaring both sides, \(^{l^2}\) + \(^{b^2}\) + 2lb = 100 Also, diagonal is 9, So, \(^{l^2}\) + \(^{b^2}\) = \(^{9^2}\) Or \(^{l^2}\) + \(^{b^2}\) = 81 Subtracting 2nd equation from 1st, we get 2lb = 19 or lb = 9.5 Area = ...

#### If the average (arithmetic mean) of b and c is 5, and the average of c and d is 10, then b - d = A. Cannot be determine

###### Problem Solving

##### Re: If the average (arithmetic mean) of b and c is 5, and the average of c and d is 10, then b - d = A. Cannot be deter

Given \(\frac{b+c}{2}\) =5

So, b+c = 10

Likewise, \(\frac{c+d}{2}\) =10

So, c+d=20

Subtracting 2nd equation from 1st,

we get b-d=-10

Answer is C.

June 25, 1982 was a friday 365 days in a regular year, which is 7X52 + 1, so if a given day is friday, then that day + 365 days is the next calendar day June 25, 1983 was thus a Saturday 1984 was a leap year, so one extra day in Feb, making June 25, 1984 a Monday (instead of Sunday) No more leap yea...
