So, we will consider what there are division options on 4. In our case it is only 7 + 13 = 20. Therefore, Rita can be 7 or 13 years old. Now it is necessary to find number which is divided into 5, proceeding from data. It is 13+2 = 15. Therefore, Rita is 13 years old, Zina is 2 years old, Ira is 7 years old, and Lyonya is 16 years old.
