Answer 2

Question:-

The mid value of a class internal is 17 and width of the class is 10. The lower limit and upper limit of the class are ?

Answer:-

⇒ Let upper limit and lower limit be x and y

⇒

$\frac{x + y}{2} = 17....1$

∴

$x + y = 17 \times 2 \\ x + y = 34 \: \: \: \: \: \:$

Now, according to the question,

⇒

$x - y = 10....2$

Adding equation ( 1 ) and ( 2 ) we get,

$∴\: 2x = 44 \\ x = 22$

And

$44 - y = 10 \\ ∴y = 34$

$∴ \: Required \: class \: interval  = 34 - \: 22.$
