В первом зале - 8 060 книг
во втором - 10 576 книг
в третьем - ?, на 347 книг меньше, чем во втором
в четвертом - ?, на 1537 книг больше, чем в первом.

Сперва узнаем сколько книг в третьем и четвертом зале. Для этого
1) 10 576 - 347 = 10 229 книг
2) 8 060 + 1 537 = 9 597 книг
Потом складываем все книги
3) 10 576 + 8060 + 10 229 + 9597 = 38 462 книги

Ответ: 38 462 книги
