Question

Несколько футбольных болельщиков соседнего дома выписывают журнал “Наш футбол”, часть жителей этого дома выписывают известный автомобильный журнал “Top Gear”, а часть тот, и тот журнал. Сколько жителей соседнего дома выписывают оба журнала, если на “Наш Футбол” подписано 64 процента, а на “Top Gear” – 84 процента?

Answer 1

48 residents

Explanation:

Let's assume that there are 100 residents in the neighboring house. 64% of the residents subscribe to "Our Football" magazine, so there are 64 residents who subscribe to it. 84% of the residents subscribe to "Top Gear" magazine, so there are 84 residents who subscribe to it. The number of residents who subscribe to both magazines can be calculated by finding the intersection of the two sets, which is equal to the number of residents who belong to both sets. This can be found using the formula:

Number of residents subscribing to both magazines = 100 - (100 - 64) - (100 - 84)

= 100 - 36 - 16

= 48

Therefore, 48 residents of the neighboring house subscribe to both magazines.
