Question

after combining 1995 and 2000 if x denotes the ratio of female commerce students to female science students and y denotes the ratio of male commerce students to male science students then​

Answer 1

Step-by-step explanation:

1995

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

30% female students = 900

65% read commerce = 1950

35% read science =1050

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

40% read science = 1440

60% read commerce = 2160

50% of male students read commerce = 1350

50% of male students read science = 1350

Famale students of science = 90

Female students of commerce = 810

x= female commerce student / female science students = 720+810/180+90= 1530/270 = 5.666...

y= male commerce students / female commerce students = 1230+1350/870+1350 = 2580/2220 = 1.162162....

x>y hence proved => 5.6>1.162
