Call the amount her sister receives, A

Then Lina's amount is A + 126

 

And 3 : 5    means that  5/3  of her sister's money = Lina's money.....so we have

 

(5/3)A   = A + 126   multiply through by 3

 

5A =  3A  + 378       subtract 3A from both sides

 

2A  = 378     divide by 2

 

A =  RM189 ....this is her sister's money

 

And Lina's money  = (5/3) 189  =  RM 315

 

Check :  Lina's Amount  - Sister's Amount 

                 315               -         189                =      126
