Answer 2

Step-by-step explanation:

✨Given:-

$\textsf{Part of the students who are boys} \implies \dfrac{5}{8} \\ \sf Number \; of \; girls \implies 540$

✨To Find:-

• The total strength of the school
• Number of boys in the school.

✨Solution:-

$\textsf{The possible outcomes are 2. Either the student} \\ \textsf{</p><p>can be a boy or a girl.}$

$\textsf{So by the above statement, we can conclude} \\ \sf that \: if \: \dfrac{5}{8} \textsf{ of the students are boys, then part of} \\ \textsf{the students who are girls will be} \\ \textsf{Part of students - Part of boys} \implies \dfrac{8}{8}- \dfrac{5}{8}=\dfrac{3}{8}$

$\therefore \sf Part \: of \: the \: Students \: who \; are \: girls \implies \dfrac{3}{8} \\ \textsf{We've been given that the number of girls are 540.} \\ \therefore \textsf{We can conclude that,} \\ \\ \sf \dfrac{3}{8}\: of \: Total \: number \: of \: students = 540. \\ \\ \sf Total \; number \: of \: students \implies \dfrac{8 \times 540}{3}=1,440$

$\therefore \sf The \: total \: strength \: of \: the \: school \: is \: 1,440.$

Now, we will find the number of boys.

$\textsf{Number of Boys = Total number of students - Number of girls} \\ \\ \textsf{Number of Boys = 1,440-540} \\ \\ \textsf{Number of Boys}= 900$
