Then make those both left joins instead of inner joins, and use nvl()... like this:

Select Trans.cTrans_fk, Sum(nvl(Payments.yAmount_paid,0)) as yAmount_paid, ;
   Sum(nvl(Charges.yCharges_amount,0)) as yCharges_amount ;
   from Trans ;
   left join Payments ;
      on Trans.cTrans_pk = Payments.cTrans_fk ;
   left join Charges ;
      on Trans.cTrans_pk = Charges.cTrans_fk ;
   group by 1

With inner joins you see only transactions where you have records in all three tables for a given transaction.
