Amda's Score Determination
We know:
Possible equal-score distributions are: \[ (1, 2, 4) \quad \text{or} \quad (3, 3, 1) \]
Zooma’s total score is 17. Since each country in the happy category secured the highest score in exactly one parameter, Zooma can have: \[ F = 7, \quad S = 6, \quad C = 4 \] Why this works:
Given the remaining scoring rules, Amda can only have: \[ (3, 3, 1) \quad \text{or} \quad (4, 2, 1) \]
Observation: No other parameter (S or C) has a score of 1 for two different countries. Thus, the score of 1 for Amda must occur in **F**.
Amda’s possible score distributions are: \[ (F, S, C) = (1, 3, 3) \quad \text{or} \quad (1, 4, 2) \] with \(F = 1\) being the fixed point across both cases.
The provided information can be depicted in the following table.
We know:
Thus, the possible equal-score combinations are: \[ (1, 2, 4) \quad \text{or} \quad (3, 3, 1) \]
Zooma’s total score is: \[ F + S + C = 17 \] Zooma is in the "happy" category, and each happy country scored the highest in exactly one parameter.
From earlier deductions and category rules, Zooma’s score in C is fixed at: \[ \boxed{C = 6} \] Given the total of 17, the remaining F and S scores must sum to: \[ F + S = 11 \] and must follow the "highest score in exactly one parameter" rule for Zooma.
Zooma’s scores are consistent with: \[ F = 7, \quad S = 4, \quad C = 6 \] or another valid split of \(F + S = 11\) satisfying the category constraints.
The provided information can be depicted in the following table.
A and C jointly obtained a total score of 7, with equal scores in all these parameters. Therefore, the possible combinations are either 1, 2, and 4 or 3, 3, and 1. Since Zooma has a score of 17, and all three countries in the happy category secured the highest score in exactly one parameter, Zooma can have a score of 7 in F, 6 in S, and 4 in C. This is because a score of 7 in S and 6 in C would be the scores of the other two countries, and Zooma cannot have a distribution of 7, 7, and 5, as there is no country that scored a 5 in C.
In the provided table, Zoom achieved the highest scores with 7 in F, 6 in S, and 4 in C. The optimal remaining scores for Benga and Dalma could be:
As it is given that both had the same total score, it can only be 15 for both, i.e., Benga’s score in S or F was one less than the maximum possible.
The provided information can be depicted in the following table.
We are told that:
Possible equal-score combinations across the parameters are: \[ (1, 2, 4) \quad \text{or} \quad (3, 3, 1) \]
- Zooma’s total score = 17. - All three countries in the happy category achieved the highest score in exactly one parameter.
If Zooma is in the happy category, then:
Given: \[ \text{Zoom} = 17, \quad \text{Benga} = 16, \quad \text{Delma} = 15 \] This distribution fits the conditions derived above and satisfies the total score requirements.
\[ \boxed{\text{Zooma: } (F=7, \ S=6, \ C=4), \quad \text{Benga: } 16, \quad \text{Delma: } 15} \]

If Benga scores 16 and Dalma scores 15 (as illustrated in the previous solution), the highest possible values that remain are:

Anu, Bijay, Chetan, Deepak, Eshan, and Faruq are six friends. Each of them uses a mobile number from exactly one of the two mobile operators- Xitel and Yocel. During the last month, the six friends made several calls to each other. Each call was made by one of these six friends to another. The table below summarizes the number of minutes of calls that each of the six made to (outgoing minutes to) and received from (incoming minutes from) these friends, grouped by the operators. Some of the entries are missing.
Operator Xitel Operator Yocel
It is known that the duration of calls from Faruq to Eshan was 200 minutes. Also, there were no calls from:
• Bijay to Eshan,
• Chetan to Anu and Chetan to Deepak,
• Deepak to Bijay and Deepak to Faruq,
• Eshan to Chetan and Eshan to Deepak.
Funky Pizzeria was required to supply Pizzas to three different parties. The total number of pizzas it had to deliver was 800, 70% of which was to be delivered to Party 3 and the rest equally divided between Party 1 and Party 2. Pizzas could be of Thin Crust (T) or Deep Dish (D) variety and come in either Normal Cheese (NC) or Extra Cheese (EC) versions. Hence, there are 4 types of pizzas: T-NC, T-EC, D-NC, D-EC. Partial information about proportions of T and NC pizzas ordered by the three parties are given below.
