Question

43 percent of students In a school are girls. If no. Of boys are 1482 then find total strength of school

Answer 1

Answer:

Let the total strength be 'x'

43% are girls , I.e number of girls = 43x/100

Total number of boys = 1482

Total number of students in school = Total number of Boys + Total number of Girls

i.e ==》 x = 1482 + ( 43x/100 )

Bring Like terms to one side

x - ( 43x/100 ) = 1482

Multiply the equation by 100

100x - 43x = 148200

57x = 148200

x = 148200/57

x = 2600

There are total of 2600 students in that school !

Answer 2

Solution

Percentage of girls in school = 43

Percentage of boys in school = 100-43 = 57%

No of boys in the school = 1482

Let the total strength of school be x

57% of x = 1482

$57\% \times x = 1482 \\ \\ \implies \frac{57}{100} \times x = 1482 \\ \\ \implies57 \times x = 1482 \times 100 \\ \\ \implies \: x = \frac{1482 \times 100}{57} \\ \\ \implies \: x = 26 \times 100 \\ \\ \implies \: x = 2600$

Therefore ,total strength of school = 2600
