Answer 1

Step-by-step explanation:

let males be x

let females be y

ATQ

x+y=15000-------------1

if female increased by 4℅

y×4/100

2y/25

y +2y/25

27y/25

if male decreased by 5℅

x×5/100

x/20

x- x/20

19x/20

27y/25+19x/20=14880

380x+108y/100=14880

380x+108y=1488000

4[95x+27y]=1488000

95x+27y=372000---------------2
