Answer:

Class mark of the class interval 40-50 is 45

Explanations:

Given class interval (46-50)

Lower limit = 46

Upper limit = 50

\boxed{\green{{class \: mark(x) = \frac{lower \: limit \: + \: upper \: limit}{2} }}}

classmark(x)=

2

lowerlimit+upperlimit

Class mark = \frac{46+50}{2}

2

46+50

⇒ x = \frac{96}{2}

2

96

⇒ x = 48

Therefore,

Class mark of the class interval 40-50 is 48
