Question

36%of the student in a school are girls. if the number of boys are 1440. find the total strength of school

Answer 1

Answer:

2250

Step-by-step explanation:

As per data

36% are girls

64% are boys

no.of boys = 1440

therefore

let total strength of school be x

then,

(64/100 )x = 1440

= 1440*100/64

=2250

therefore total strength of the class is 2250

Answer 2

Answer:2250 girls and boys

Step-by-step explanation:

Let the total strength be x

this implies that,

=36 percent of x + 1440= x

=36 x/100+1440 =x

=36 x/100= x-1440

=36 x= 100(x-1440)

=36 x= 100 x-144000

=144000= 100 x-36 x

=144000= 64 x

∴x = 144000/64

∴x =2250

∴girls=810

∴boys=1440
