1st Question
Number of invalid votes by the female voters = number of votes polled by the females- number of valid votes polled by the females.
= (453-226)-187=227-187=40 millions.
The required percentage=(40/227)X100=17.6%
ans:- Choice 3
2nd Question
Valid votes in 1995= valid votes polled by males+valid votes polled by females= 233+219=452.
Valid votes in 2000=269+254=523
Percentage increase= (523-452)/452 X100= 15.7%
Ans:- Choice 1
3rd Question
Invalid votes= total number of votes polled - total number of valid votes polled by males and females.
Invalid votes in 1985= 453-(187+196)=70.
The required ratio in 1985= 70/453=1/6
Similarly the required ratio in 1990= 72/503=1/7
In 1995=131/583= 1/4
In 2000= 148/671=1/4
1/7 is the least. Hence the required percentage is the least in 1990.
Ans:- Choice 2
4th Question
Number of invalid votes polled by males= 329-254=75 millions.
Number of invalid votes by the females=(671-329)-269)= 73 millions.
The required difference = 75-73= 2 millions.
Ans:- Choice 1
5th Question
The ratio of number of votes polled by males to the total number of votes polled will hold good for a comparison of the ratio of the number of votes polled by males to that polled by female.
Therefore the required ratio In 1985 = 226/453 = 1/2
In 1990 = 248/503
In 1995= 281/583
In 2000= 329/671
226/453 is much closer to half where as other fractions are much less that 1/2.
Hence the ratio in 1985 was the greatest.
Ans:- Choice 1
