Answer:

Class mark of the class interval 40-50 is 45

Explanation:

Given class interval (40-50)

Lower limit = 40

Upper limit = 50

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

classmark(x)=

2

lowerlimit+upperlimit)

classmark=40+502class \: mark = \frac{40+50}{2}classmark=

2

40+50

⟹x=902\implies x = \frac{90}{2}⟹x=

2

90

⟹x=45\implies x = 45⟹x=45

Therefore,

Class mark of the class interval 40-50 is 45
