Answer 1

С + О = 11   С = 11-О
О + П = 15   С = 15-П
С + П = 14   
(11-О) + (15-П) = 14
2О = 12
О = 6 Олимпиада выпила 6 чашек чаю
С = 11-О  11-6 = 5   Сосипатра выпила 5 чашек чаю
П = 14-С   14-5 = 9 Поликсена выпила 9 чашек чаю

6+5+9 = 20 чашек выпили вместе

Answer 2

(11+15+14)÷2=20-чашек чая выпили они вместе
20-15=5-чашек чая выпила Сосипатра
11-5=6-чашек чая выпила Олимпиада
14-5=9-чашек чая выпила Поликсена
Ответ:9 чашек чая выпила Поликсена.

Problem Analysis

We have three merchants named Sosipatra Titovna, Olimpiada Karpovna, and Poliksena Uvarovna who are sitting together to drink tea. Olimpiada and Sosipatra drank 11 cups of tea together, Poliksena and Olimpiada drank 15 cups together, and Sosipatra and Poliksena drank 14 cups together. We need to determine how many cups of tea were consumed by the three merchants together and how many cups each merchant drank individually.

Solution

Let's solve this problem step by step.

1. Determine the total number of cups of tea consumed by the three merchants together: - Olimpiada and Sosipatra drank 11 cups together. - Poliksena and Olimpiada drank 15 cups together. - Sosipatra and Poliksena drank 14 cups together. To find the total number of cups of tea consumed by the three merchants together, we need to add up these three values: 11 + 15 + 14 = 40 cups of tea.

2. Determine how many cups of tea each merchant drank individually: - Olimpiada and Sosipatra drank 11 cups together. - Poliksena and Olimpiada drank 15 cups together. - Sosipatra and Poliksena drank 14 cups together. To find out how many cups each merchant drank individually, we need to subtract the cups they drank together from the total number of cups they drank with the other merchants: - Olimpiada: Total cups - Cups with Sosipatra - Cups with Poliksena = 40 - 11 - 15 = 14 cups of tea. - Sosipatra: Total cups - Cups with Olimpiada - Cups with Poliksena = 40 - 11 - 14 = 15 cups of tea. - Poliksena: Total cups - Cups with Olimpiada - Cups with Sosipatra = 40 - 15 - 14 = 11 cups of tea.

Answer

The three merchants together drank 40 cups of tea. Each merchant individually drank the following number of cups: - Sosipatra Titovna: 15 cups of tea. - Olimpiada Karpovna: 14 cups of tea. - Poliksena Uvarovna: 11 cups of tea.
