Answer 2

Answer:

Rs.5400

Step-by-step explanation:

Let the sum be Rs.100

Amount in 2 yrs=Rs.6593.40

r1=10%,r=11%

For the 1st year=

                         I=P*T*R1/100

                         =100*1*10/100

                         =Rs.10

Amount =P+I

             =100+10

             =Rs.110

For 2nd year:

          I=P*T*R2/100

         =110*1*11/100

         =Rs.12.1

Amount=110+12.1

             =Rs.122.1

For Rs.100 ------Amount is Rs.1221.1

For Rs. x----------Amount is Rs.6593.40

So on solving we will get ----Rs.5400
