Answer»

Ratio of salaries of DANNY, Bravo and Casillas = 3 : 5 : 9

Part of salary of Danny = 3x

Part of salary of Bravo = 5x

Part of salary of Casillas = 9x

Increased part of salary of Danny = 55% of 3x = $(\frac{{55}}{{100}} \times 3x = 1.65x)$

Increased part of salary of Bravo = 50% of 5x = (50/100) × 5x = 2.5x

Increased part of salary of Casillas = 75% of 9x = (75/100) × 9x = 6.75x

New ratio of salaries of Danny, Bravo and Casillas = (3 + 1.65)x : (5 + 2.5)x : (9 + 6.75)x = 4.65 : 7.5 : 15.75 = 465 : 750 : 1575 = 31 : 50 : 105.
