#### 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**
