Answer:

Let, the sum of money be 'x'


∴S.I.= (P×R×T)/100


      =(X×4×4)/100


      =16 X/100


      =4 X/25


    ∴  Amount =(X + 4 X /25)    


                      =(25 X+4 X)÷25


                       =29 X/25


By condition,


29 X/ 25 =1044


⇒29 X =1044×25


⇒X =(1044×25)÷29


⇒X= 36×25


⇒X=900


∴The sum of money is Rs.900
