Question

find thecompound interest on R
s2000@12percent p.a .for 4years 3months​

Answer 1

Answer:

compound interest is Rs.961.

Explanation:

Principal (P)=Rs.4000

Rate of Interest (r)=10%

Time =2 years and 3 months

Here, first we take n=2 years

A=P(1+  100 r  )  n

 

Where,  

A= Amount and n= number of years

⇒A=4000(  10 11  )  2

 ⇒A=4000×  100 121

​⇒A=Rs.4840

The Amount after two years =Rs.4840

Now,  

Principal =Rs.4840

Simple interest for last 3 month, i.e.,  

4 1  year =  100

PRT  =  100 4840×10×  4 1

​ =Rs.121

Therefore,

Amount after 2 years and 3 months =4840+121=Rs.4961

Therefore,

C.I.=A−P

⇒C.I.=4961−4000=Rs.961

Hence the compound interest is Rs.961.
