Question

Upper limit of class $'41 - 50'$is _______.
$
  (a)\,\,41 \\
  (b)\,\,50 \\
  (c)\,\,45 \\
  (d)\,\,91 \\
 $

Answer 1

Hint: Every given interval has two values one tell from where and other tell up to which we can take values.
The number from which we can take values is called the lower limit and written on the left side of the interval and the number up to which we can take the maximum is called the upper limit and written on the right side of the interval.

Complete step-by-step answer:
The lower class limit of a class is the smallest data value that can go into the class. The upper class limit of a class is the largest data value that can go into the class. Class limits have the same accuracy as the data values; the same number of decimal places as the data values.
First step to look out the class limit of a given class interval.
The largest value of the given class is its upper-limit of class.
The upper-limit of class can be obtained as,
\[
  {\text{In a class of }}'41 - 50' \\
  {\text{Upper Class limit = 50}} \;\
 \]
Thus, the upper-limit of class \['41 - 50'\] is 50.
So, the correct answer is “Option B”.

Note: In statistics problem when interval is given. Each interval has two number one at left side and other at right side. Also, intervals represent the range from where to what we can take. So, from this we conclude the right side number of Interval is the maximum limit and name as the upper limit of the interval.
