difference between the initial number of male and
female students in college?​

Answer 1

Answer:

24

Step-by-step explanation:

given:-

initial number of students= 13200

solutions:-

suppose number of male student =X

then number of female student = 13200-x

after increased

•male = x+ 30x/100

= 13x/10

•female= x+20x/100

= 6x/5

there are 16440 students in college after the increasing of students so--

total student = 13x/10 + 6x/5= 16440

=( 13x +6x × 2)/10=16440

= 25x/10= 5x/2= 16440

x=16440×2/5= 3288×2= 6576 male student

hence there were

x = 6576 male student in initial

13200-6576= 6624 female student

so difference = 6624-6576= 24
