Question

In co-educational school , 45% of the total student are girls If there are 440 boys in the school , find the number of girls in the school

Answer 1

Answer:

360

Step-by-step explanation:

Given Number of girls = 45%.

          Number of boys = 55% = 440.

if 55% = 440

Then 1% = 440/55

Then 45% = (440 * 45)/55

                 = 360.

Number of girls in the school = 360.

percentage of girls=45%

percentage of boys =55%(100%-45%)

number of boys=440

$1\% \: girls \: = \frac{440}{55}$

$= > 1\% \: of \: girls = \frac{8}{1} \\ = 8$

$45\% \: of \: girls \: = 8 \times 45$

$= 360$
