Answer 1

Answer:

$\huge\underbrace\mathcal\purple{ANSWER}$...

Let a be lower class limit, l is the upper class limit and m is the mid-point

then, mid-point m= a+1/2

Therefore, a=2m−l

Answer 2

Answer:

$\huge\red{\mid{\fbox{\tt{ANSWER}}\mid}}$

Let a be lower class limit, l is the upper class limit and m is the mid-point

then, mid-point m= a+1/2

Therefore, a=2m−l
