2014 . If the average (arithmetic mean) of 16, 20 and n is between 18 and 21 inclusive, what is the greatest possible value of n ?

A. 18
B. 21
C. 27
D. 54

View Answer	Favorite Question

Answer: Option C

Explanation:

we must take such a value of n for which the average must be in between 18 to 21, inclusive. It means 21 can be the average . We are looking fro greatest value of n. So, we must take 21 as average of this 3 numbers.

16 + 20 + n = 3×21

= > 36 + n = 63

∴n = 27.

A. m+n
B. m-n
C. m/n
D. mn

View Answer	Favorite Question

Answer: Option D

Explanation:

Average of m numbers n^2

So, Sum of m numbers= mn^2

Average of n numbers m^2

So, sum of n numbers= nm^2

Now,

Sum of (m+n) numbers= mn^2+nm^2 = mn(m+n)

Average of (m+n) numbers= {mn(m+n)}/(m+n) = mn

Ans: mn.

Answer: Option A

Explanation:

The third number is the average number of 5 consecutive integers.

So, the smallest integer is = 12 - 2 = 10

2023 . If the average of 5 consecutive integers is 15 then what is the difference between the least and the greatest of the 5 ingers?

A. 4
B. 5
C. 8
D. 10
E. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

Let's denote the five consecutive integers as x, x + 1, x + 2, x + 3, and x + 4, where x is the smallest integer among them.

According to the given information, the average of these integers is 15. So, we can write the equation:

(x + x + 1 + x + 2 + x + 3 + x + 4) / 5 = 15

Now, let's simplify this equation:

(5x + 10) / 5 = 15

Now, multiply both sides of the equation by 5 to isolate 5x:

5x + 10 = 15 * 5

5x + 10 = 75

Subtract 10 from both sides:

5x = 75 - 10

5x = 65

Now, divide by 5:

x = 65 / 5

x = 13

So, the smallest integer is 13, and the greatest integer is x + 4 = 13 + 4 = 17.

The difference between the greatest and the least of the 5 integers is:

17 - 13 = 4

Therefore, the difference is 4.
