The number of books on Mathematics, Physics and Chemistry in a University library is in the ratio 8 ∶ 5 ∶ 9.
Calculation:
Let the number of books be 8a, 5a and 9a
New ratio = 8a × 110% : 5a × 105% : 9a × 105%
⇒ 8a × 22 : 5a × 21 : 9a × 21
⇒ 176 : 105 : 189
∴ The ratio of the number of books after the increment is 176 : 105 : 189.
