Question

find the class mark in between 10-15 interval

Answer 1

$Given \: class \:interval : \: ( 10 - 15 )$

$Lower \: limit = 10$

$Upper \: limit = 15$

$\boxed { \pink { Class \:mark = \Big (\frac{Lower\: limit +Upper \:limit }{2}\Big) }}$

$\implies \red { Class \: mark } = \frac{10+15}{2} \\= \frac{25}{2} \\= 12.5$

Therefore.,

$\red {Class \: mark }\green { =12.5 }$
