120%   = 6/5

Call the amount save by Charles = A

The amount saved by Bala = (5/4)A

The amount saved by Ali = (6/5)(5/4)A =  (3/2)A

And we're told that

A + 120 = (3/2)A     subtract A from both sides

120 = (1/2)A    multiply both sides by 2

\$240 = A  this is what Charles saved

And Baa saved (5/4)(240)  = \$300

And Ali saved (3/2)A = \$360
