Answer(s)

Sol:-

amount=Rs.364500

principal= Rs.500000

rate of decreasement=10%

now,

        A=P(1-R/100)n

        364500                 =500000(1-10/100)n

        364500/500000  =(10-1/10)n

        729/1000                =(9/10)n

        9/10)3                      =(9/10)n

 

When bases are same we equate power,  So

n=3

Hence, the time taken is 3 years
