The least possible value of n is 27.
According to the statement
We have given that the set which is {2,4,6,8.....n} and and one set is removed from them the average of remaining integers is 28.
Then
Firstly set contain n numbers
But after that set contain n-1 numbers after removal of 1 digit from them.
and average value of remaining digit is 28 then 28th term become after removal is
28th term =28*2
28th term = 56.
then
we use the formula to calculate n
n-1 =28
then the value of n become 27.
the least possible value of n is 27.
So, The least possible value of n is 27.

Simple....
you have the variable isolated..simply divide or simplify...
4x=14
x=3.5
Also,
x=
Thus, your answer.
The trapezoids are similar which means the bigger one is a multiple of the smaller one.
compare the like sides to see the multiple is 4
20 = 5x
4 = x
the sides of ABCD are 4 times bigger than EFGH
**Area is not directly related
The area of a trapezoid = h(a+b)/2
where a and b are the top/bottom sides
A = 4h * 4(a+b)/2
A = 16 * h(a+b)/2
Then the area of ABCD is:
= 16 * 40 cm²
= 640 cm²
