60% students in a school are boys find total number of students in a school if 120 are girls​

Answer 1

Total no of students= x

% of boys=60%

% of girls= 40%

No of girls =120

40% of x= 120

x=(120 X 100)/40

x=300

Therefore, total no of students= x=300

Answer 2

Answer:

300 students

Step-by-step explanation:

Percentage of boys = 60

Percentage of girls = (100 - 60) = 40 (since in percentages, 100 is considered as the whole)

No. of girls = 120

Let x be the no. of students in the school.

By the problem, we get

$\frac{40}{100}x = 120$

(as percentage means out of 100, so, in equations, we have to replace the percent symbol and write 100 in the denominator)

$\frac{2}{5}x = 120$

$x = 120 \times \frac{5}{2}$

$x = 60 \times 5$

$x = 300$

Hence, there are 300 students the school.
