Question

Two mothers and two daughters went shopping. Each bought a DVD with a favorite film and they brought home 3 DVDs. How can thet be?

Answer 1

Напишу на русском: 2 матери и 2 дочери(дочь,мать,бабушка)(допустим: Х,У,С...У и дочь и мать,С и дочь и мать)
These peoples are daughter, mum and grandmother

Answer 2

The scenario described can be explained as follows:

The two mothers are also the two daughters. This means that there are only three individuals involved: a grandmother (Mother 1), her daughter (Daughter 1), and her granddaughter (Daughter 2).

So, when it is stated that "two mothers and two daughters went shopping," it means that the grandmother (Mother 1) went shopping with her daughter (Daughter 1) and her granddaughter (Daughter 2). Each of them bought a DVD with their favorite film, which accounts for three DVDs in total.
