2)the question is not correct

Answer 2

Answer:

1. 7
2. 800/x

Step-by-step explanation:

1. Let the number=x

Half Century= 50

ATQ,

x×x= 50-1

x²=49

x=√49

x=7

The number is 7

2. The no. of days depends upon the no. of pages he reads in a day, which is not mentioned in the question.

Let the no. of pages he reads in a day=x

Total pages= 800

No. of days= $\frac{800}{x}$

Number of days in which he finishes the book= 800/x
