Answer 1

Given,
$%$ of students who like cartoon movies $= 65$
$%$ of students who like horror movies $= 70$

$%$ of students who like war movies $= 75$

$\Rightarrow %$ of students who dose not like cartoon movies $= (100 - 65) = 35$

$\Rightarrow %$ of students who dose not like horror movies $= (100 - 70) = 30$

$\Rightarrow %$ of students who dose not like war movies $= (100 - 75) = 25$

$\Rightarrow$ Maximum $%$ of students who dose not like any movies $= (35 + 30 + 25) = 90$

$\Rightarrow$ Smallest $%$ of students liking all three types of movies $= (100 - 90) = 10$
