Ken's savings was 2/5 of Edwin's savings. After Ken increased his savings by 20% and Edwin's savings decreased by 55%, Ken's savings was $600 more than Edwin's. What was Ken's savings in the end?

K=2/5*E

2/5*E*1.2-600=E*.45

.48*E-600=.45*E
600=.03*E

E=20000

 

You can work out Ken's savings in the end by yourself :)

Let x be Edwin's savings

2/5x be Ken's savings

2/5x + 20%(2/5x) + x - 55%x + $600

0.4x + 0.08x = 0.45x + $600

0.48x - 0.45x = $600

0.03x/0.03 = $600/0.03

       x = $20000

2/5 ($20,000) + 20% (2/5($20,00)) = $9600
