3. 1)
40,000+40,000*x/100=38,000+38,000*y/100
the sum of their augmentation is 12,000 ,so we have

40,000*x/100+38,000*y/100=12,000
400x+380y=12,000
20x+19y=600

from the first equation,you will get
20x-19y=-100
you do combination and you will get
40x=500
4x=50
x=12.5

19y=600-20(12.5)
19y=600-250
19y=350
y=18.4
the first will get an augmentation of 12.5%
the second 18.4%
