Answer 1

Answer:

Step-by-step explanation:

1st day=3/5

2nd day=4/5

total=3/5+4/5+30

Answer 2

Answer:

375

Explanation:

Let the total number of pages be x.

Pages read on first day = 3/5 x

Remaining pages = 2/5 x

Pages read on second day = 4/5 of 2/5 x = 8/25 x

Remaining pages = 2/5x - 8/25x = 2/25x

According to Question,

2/25 x = 30

x = 375

Hence, the book contained 375 pages.
