Answer:

1. 185.71% 2. 30.56%

Explanation:

(1) Initial no of books = 14

Final no of books = 40

Increase in books = 40-14 = 26


\%\ \text{increase in books}=\frac{\text{increase in books}}{\text{initial no of books}}* 100\\\\=(26)/(14)* 100\\\\=185.71\%

(2) Initial points = 72

Final points = 50

Decrease in points = 72-50= 22


\%\ \text{decrease in points}=\frac{\text{decrease in points}}{\text{initial points}}* 100\\\\=(22)/(72)* 100\\\\=30.56\%

Hence, this is the required solution.
