Salary of A,B and C in ratio 1:3:4.
Let the salary of A is Rs 100 then the salaries of B and C are Rs 300 and Rs 400
The salary of A increases by 5% then salary of
A =100+(100×5/100) = Rs 105
The salary of B increases by 10% then salary of
B = 300+(300×10/100) = Rs 330
The salary of C increases by 15% then salary of
C = 400+(400×15/100) = Rs 460
Then new ratio of salary A,B, andC
=105 : 330 : 460
=21 : 66 : 92. (ans.)
