Answer:
A - Solomon read
of the book each night.
B - The total number of pages in the book are 105.
Step-by-step explanation:
We are given that,
Solomon has read
of a book.
So,
of the book is left to be read.
Ques A: We have that,
In 5 nights, Solomon read
of the book.
So, on 1 night, he will read,
=
of the book.
Thus, Solomon read
of the book each night.
Ques B: Let the total pages of the book = x.
Solomon reads 14 pages in 1 night. So, he reads, 14 × 5 = 70 pages in 5 nights.
Since, these 70 pages represent the
of the book, he read in 5 nights.
So,
of the total pages = 70
i.e. 
i.e. x= 105
Hence, the total number of pages in the book are 105.
