A) 20: 66: 95
B) 21: 66: 95
C) 21: 66: 92
D) None of these
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
