Answer 1

Answer:

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 300) = 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 : 460 = 21 : 66 : 92
