Answer:
Answer:
15:11
Step-by-step explanation:
Let no. of boys and girls in junior section be 9x and 7x , respectively.
A/Q,
=>9x+7x = 320
=> 16x = 320
=> x = 320/160
=> x = 20
No. of boys in junior section= 9x
9×20 = 180
No. of girls in junior section= 7x
7× 20 = 140
Let no. of boys and girls in senior section be 3x and 2x , respectively
A/Q,
=>3x+2x=200
=>5x=200
=>x=200/5
=>x=40
No. of boys in senior section= 3x
3×40 = 120
No. of girls in senior section = 2x
2×40 = 80
• Total no. of Boys in school= 180+120
=> 300
• Total no. of Girls in school= 140+80
=> 220
Boy: Girls
=> 300:220
=> 15:11
