Question

If 80% students of a class of 45 students like to play cricket then how to many don't like to play cricket​

Answer 1

$\text{The Total number of students in a class} = 45$

$\text{Percentage of students who like to play cricket} = 80 \%$

$\text{We know that Percentage} = \dfrac{\text{Given Value}}{\text{Total Value}} \times 100$

$\implies \text{Number of students who like to play cricket} = \dfrac{80}{100} \times \text{Total students}$

$\implies \text{Number of students who like to play cricket} = \dfrac{80}{100} \times 45$

$\implies \text{Number of students who like to play cricket} = \dfrac{4}{5} \times 45$

$\implies \text{Number of students who like to play cricket} = 36$

$\implies \text{Number of students who don't like to play cricket} = \\\text{Total} - (\text{Number of students who like to play cricket})$

$\implies \text{Number of students who don't like to play cricket} = 45 - 36$

$\implies \boxed{\text{Number of students who don't like to play cricket} = 9}$
