Let W1=Sam's Income, W2=Ben's Income
Let L1=Sam's Living Cost, L2=Ben's Living Cost
W1/W2=2/1 ---> W1=2W2
L1/L2=9/4 ---> L1=(9/4)L2
W1-L1=100 ---> W1=L1+100
W2-L2=100 ---> W2=L2+100
(L1+100)/(L2+100)=2/1
L1+100=2L2+200
(9/4)L2+100=2L2+200
100=(1/4)L2
L2=400
So W2=500
Therefore, Sam's income is $1000, Ben's income is $500
