Solution:

Number of commuters travelling on route A
=

{4000×20}/{100}

= 800
Males ⇒

3/8

× 800 = 300
Females ⇒

5/8

× 800 = 500
Number of commuters travellingon route F
= 4000 ×

{12}/{100}

= 480
Males ⇒

2/3

× 480 = 320
Females ⇒ 480 - 320 = 160
∴ Required ratio = (300 + 320) ×

{20}/{100}

; (500 + 160) ×

{20}/{100}

= 620 : 660 = 31 : 33
