• D. 25:7:12:11
• E. 25:7:11:12

Answer 1

The correct option is B 25:12:7:11

Ratio of salaries of A,B,C and D at the end of 2003 = 22:13:7:13
$\therefore$ Ratio of salaries of A,B,C and D at the end of 2006 = 125% of 130% of 120% of 22 :110% of 120% of 120% of 13 :120% of 130% of 110% of 7 : 120% of 110% of 110% of 13
$125\times 130\times 22:110\times 120\times 13:130\times 110\times 7:110\times 110\times 13$
$125\times 22:11\times 120:110\times 7:110\times 11=25:12:7:11$
