principle = rs. 2800
time = 4years
rate = 13/2 %
simple interest = (principle * rate * time )/100
= (2800*4*13)/(100*2)
= 14*4*13
= rs . 728

principle = rs. 6550
time =5 years
rate = 8 %
simple interest = (6550*5*8)/100
= 655*4
= rs. 2620

total earning = rs. 728+ rs. 2620
= rs. 3348

We have Principle P = 2800
                    
Rate  r =13/2 %
                    Time  n = 4 yr                  
 interest =  P*r*n

             = 2800*13*4/200
             = 728

For  the second lending
     P =  6550
     r  = 8 %
     n = 5 yr
interest = 6550*8*5/100
            =  2620
Her Total earning will be the sum of interests
                            = 728 + 2620

                            =  3348

Her Total earning will be Rs 3348
