Question

In a continuous frequency distribution, class mark of a class is 85 and lower limit is 83, then its
upper limit is​

Answer 1

Answer:

87

Step-by-step explanation:

classmark=85

lower limit=83

class mark=upper limit +lower limit/2

upper limit=classmark*2 -lower limit

                  =85*2-83

                  =170-83

                 =87        

upper limit=87

Answer 2

Answer:

The correct answer is : Upper limit $=87$

Step-by-step explanation:

First, let us consider the given values.

Class mark$=85$

Lower limit $=83$

We know that the formula for class mark is : $\frac{upper limit+lower limit}{2}$

Here, we need to find the upper limit.

Upper limit $=2*class mark-lower limit$

$=85*2-83\\ =170-83\\ =87$

Hence, the upper limit is $87$.

Continuous frequency distribution:

A series in which the data are divided into distinct class intervals without gaps and their respective frequencies are assigned in accordance with the class intervals and class breadth is known as a continuous frequency distribution.
