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
elimimate 1&2
