Question 10(c)

In a college out of 4320 students, 2300 are girls. Find the ratio of:

The number of boys to the total number of students.

Answer 1

Total number of students in school = 4320

Number of girls = 2300

Therefore, number of boys = Total number of students - Number of girls

= 4320 - 2300 = 2020

Ratio of number of boys to total number of students

= $\frac{Numberofboys}{Totalnumberofstudents}$

= $\frac{2020}{4320}$ = $\frac{101}{216}$ = $101:216$ [Dividing numerator and denominator by HCF of 2020 and 4300 i.e. 20]
