Answer 1

Step-by-step explanation:

Let the number of students be x

the number of boys=x×70/100

=7x/10

the number of girls=x×30/100

=3x/10

after 32girls come the total girls=3x/10+32

after 32 boys left total boys=7x/10-32

A/q

or, 54% of x=7x/10-32

or,54x/100 =7x/10-32

or,54x/100-7x/10= -32

or,-16x/100 =-32

or,x = -32×100/-16

or,x=2×100

or,x=200
