ANSWER IS        $ 600  she have left



Kelly invested $1,500

She lost 1/3 of it by the end of January 

she lost by the end of January = 1/3 * $1,500

                                                 =   $ 500

so she has 1500 - 500 =  $ 1000  by the end of january


now she has lost 2/5 of the remaining amount by the end of February

 that is  she has lost 2/5 of the  $1000 by the end of February

     2/5  * 1000 = $ 400 lost   by the end of February


 she have left at the end  =  1000 - 400 

                                        =  $ 600


so answer is   $ 600   she have left at the end......


hope you understood..please message if you have any doubts,,thank you
