Question

Rs 20000 is being compounded at 20%p.a.if the rate of interest is charged half yearly.what will be the amount of 2 yrs.

Answer 1

Hey mate here is your answer
A=P(1+R/100) n
=20000(1+20/100)2
=20000*120/100*120/100
=28800
CI=A-P
=28800-20000
=8800 ans
Hope it helps

Answer 2

Given Data: Rs20000, 20%, 2 years.

To find: The amount for 2 years.

Solution:

• Compound interest is calculated with the amount that is initial principal and the given interest.
• Formula of  Compound Interest is,

                                 $A = P(1+ \frac{r}{100} )^{n}$.

A = Amount, P = principal,  r = rate interest, n = no of time or years,    

• Here P = 20000, r = 20%, n = 2.

                               $A = 20000(1+\frac{20}{100})^{2}$.

                               $A = 20000(1.2)^{2}$

                                $A = 28800$.

• Hence the amount of 2 years for given data = 28800.
