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%
