Q. After combining 1995 and 2000 if x denotes the ratio of female commerce student to female Science student and y denotes the ratio of male commerce student to male Science student, then

Detailed Solution for Test: Statistical Description Of Data - 2 - Question 28

The correct option is Option A.

1995

70% male students = 2100 (70% of 3000)

30% female students = 900

20% of female read science = 180

80% of female read commerce = 720

Male students read commerce = 1230 (1950 - 720)

Male students read science = 870

2000

75% male students = 2700 (75% of 3600)

25% female students = 900

50% of male students read commerce = 1350

50% of male students read science = 1350

Female students of science = 90

Female students of commerce = 810

x = female commerce students / female science students

= 720 + 810 / 180 + 90

= 1530 / 270

= 5.666

y = male commerce students / female commerce students

= 1230 + 1350 / 870 + 1350

= 2580 / 2220

= 1.162

So, x > y

Hence proved
