Question

The ratio of salaries of A, B and C is 1:3:4. If their salary is increased by 5%, 10% and 15% respectively, then in what ratio will their salary increase?​

Answer 1

Answer:

Step-by-step explanation:

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%↑===> 105(A's increased salary);

300 (B's salary)===10%↑===>330 (B's increased salary);

400 (C's salary)===15%↑===> 460 (C's increased salary).

Ratio of their increased salary = 105:330:480 = 21:66:92
