Simple Happiness Index
CAT 2017 Slot 1 · DILR · Hard · Data Interpretation
Passage / data set
Simple Happiness index (SHI) of a country is computed on the basis of three parameters: social support (S), freedom to life choices (F) and corruption perception (C). Each of these three parameters is measured on a scale of 0 to 8 (integers only). A country is then categorized based on the total score obtained by summing the scores of all the three parameters, as shown in the following table:
| Total Score | 0-4 | 5-8 | 9-13 | 14-19 | 20-24 |
|---|---|---|---|---|---|
| Category | Very Unhappy | Unhappy | Neutral | Happy | Very Happy |
Following diagram depicts the frequency distribution of the scores in S, F and C of 10 countries - Amda, Benga, Calla, Delma, Eppa, Varsa, Wanna, Xanda, Yanga and Zooma:
Frequency distribution of scores:
- Score 1: S = 0, F = 2, C = 1
- Score 2: S = 0, F = 1, C = 3
- Score 3: S = 3, F = 2, C = 4
- Score 4: S = 3, F = 1, C = 1
- Score 5: S = 2, F = 3, C = 0
- Score 6: S = 1, F = 0, C = 1
- Score 7: S = 1, F = 1, C = 0
Further, the following are known:
- Amda and Calla jointly have the lowest total score, 7, with identical scores in all the three parameters.
- Zooma has a total score of 17.
- All the 3 countries, which categorized as happy, have the highest score in exactly one parameter.
Question 1 of 4
What is Amda's score in F?
1
Explanation
Lowest score = 7 for Amda and Calla. The only combination of scores that sums to 7 and matches frequencies is S=3, F=1, C=3. Thus Amda's score in F is 1.
Question 2 of 4
What is Zooma's score in S?
6
Explanation
Zooma's total score is 17. The parameters that sum to 17 are S=6, F=7, C=4. Thus Zooma's score in S is 6.
Question 3 of 4
Benga and Delma, two countries categorized as happy, are tied with the same total score. What is the maximum score they can have?
- A.
14
- B.
15
- C.
16
- D.
17
B
Explanation
The maximum possible tied total score for Benga and Delma under the Happy category (14-19) constraints is 15.
Question 4 of 4
If Benga scores 16 and Delma scores 15, then what is the maximum number of countries with a score of 13?
- A.
0
- B.
1
- C.
2
- D.
3
B
Explanation
Allocating the available parameter scores among the remaining countries leaves at most 1 country with a score of 13.
