The salaries of A, B and C are in the ratio 1:3:4. If the salaries are increased by 5%, 10% and 15% respectively, then the increased salaries will be in the ratio  Choose the correct answer:
A) 20:66:95
B) 21:66:96
C) 21:66:92
D) 19:66:92
E) None
Solution: Let A's Salary = Rs. 100   Then, B's Salary = Rs. 300   And, C's Salary = Rs 400   Salary has given in 1:3:4 ratio.   Now,   5% increase in A's Salary,   A's new Salary = (100 + 5% of 100) = Rs. 105.   B's Salary increases by 10%, Then,   B's new Salary = (300 + 10% of 200) = Rs. 330.   C's Salary increases by 15%,   C's new Salary = (400 + 15% of 400) = Rs. 460.   Then, ratio of increased Salary,   A:B:C = 105:330:460 = 21:66:92.   Alternative   100(A's salary)===5%↑===&gt; 105(A's increased salary);   300 (B's salary)===10%↑===&gt;330 (B's increased salary);   400 (C's salary)===15%↑===&gt; 460 (C's increased salary).   Ratio of their increased salary = 105:330:480 = 21:66:92   Answer: Option 21:66:92
