Salaries of A, B and C were in the ratio of 3 : 5 : 7 respectively. If their salaries were increased by 50%, 60% and 50% respectively, what will be the new ratio of their respective salaries?  Answers:
A) 3 : 6 : 7 B) 4 : 5 : 7 C) 4 : 5 : 8 D) Data inadequate E) None of these
Suppose the salaries of A, B and C were 300k, 500k and 700k respectively.   After increment salary of   A = 300k + 50% of 300k = 450k   B = 500k + 60% of 500k = 800k   C = 700k + 50% of 700k = 1050k   Hence, new ratio of the respective salaries of A, B and C = 450k : 800k : 1050k = 9 : 16 : 21   Answer None of these
