Answer 2

given - let population of male be x and female be y.

case 1

x+y=90000 ...... 1

case 2

x =2/3 y ...... 2

substitute equn 2 in equn 1

2/3y + y = 90000

2y + 3y = 270000

5 y = 270000

y = 270000/5

y = 54000

x= 2/3 ×54000

x= 36000

verify ---

x=2/3y

36000= 2/3 × 54000

36000 = 36000
