XAT 2015 — QA & DI Question 28
Answer the following questions on the basis of information given below.
Twitter allows its users to post/share and read short messages known as tweets. Tweets can be of three types – Positive Tweets (in support), Negative Tweets (against) and Neutral Tweets. The following table presents the Number of Votes and Tweets received by certain political parties.
âââââââ
* Any party which has secured less than 2% of the total votes falls under ‘Other Parties’ category. For example, Party E secured less than 2% of total votes, in the year 2000.
Note: If the vote share (%age of total votes) of a party changes from 15% to 40%, gain in vote share would be 25% (= 40%, –15%).
Between 2000 and 2010, in terms of gain in vote share which of the following cannot be a possible value (approximated to one decimal place) for any party?
Answer & solution
- A
2.0%
2.5%
- C
3.5%
- D
4.5%
- E
7.5%
E secured less than 2% i.e. (0% to 2%) of the total votes in the year 2000.
The following table represents the individual vote shares and the gain in vote shares of parties A to E,
âââââââ
The values 2% and 7.5% already exist in the table.
E’s gain in vote share can have any value from 3% to 5%. The values 3.5% and 4.5% may exist within this range.
However, it is not possible to obtain 2.5% as the gain in vote share for any party.
Hence, option (b).
