Answer: 2:4:3
Step-by-step explanation:
Let A's initial salary be x. B's initial salary be y and C's initial salary be z.
A's new salary=20%+x=6x/5
B's new salary= y-10%=9y/10
C's new salary=z+10%=11z/10
Now, 6x/5:9y/10:11z/10=8:12:11=8k:12k:11k
This means that 6x/5=8k
X=20k/3
9y/10=12k
Y=40k/3
11z/10=11k
Z=10k
Now A:B:C
= 20k/3:40k/3:10k
=20/3:40/3:10/3
=20:40:30
=2:4:3
