Reasons:

4. In order to solve it use
(x +y)2 + (x – y)2 / x2 +y2 = 2
5. x2 = 625, x = 25
6. On first day = 3/5 (A)
Remaining part = (1 – 3A/5) = 2A/5
On second day = 3/8(2A/5) = 3A/20
Unread = 1 – (3A/5 + 3A/20) = 1 – (12A + 3A)/20
= 1 – 15A/20 = 5A/20
= A/4
8. 5/2= (5/2 × 100)% = (25)%
9. 40% = 40/100 = 2/5
