Question

Raju Invests Rs 12,800 for three Years at the rate of 10% Per annum Compounded Annually . Find the Total sum of Raju At the end of First Year .

Answer 1

Answer:

A = Rs. 14080

Step-by-step explanation: (With Formula)

P = Rs. 12,800

r = 10% p.a.

n = 3 years

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

$A = 12800\ (1 + \frac{10}{100} )^{1}$

$A = 12800\ (\frac{110}{100} )^{1}$

$A = 12800$ × $\frac{110}{100}$

$A = 128$ × $\frac{110}{1}$ (After cancellation of zeros)

A = Rs. 14080

Step-by-step explanation: (Without Formula)

$P_{1}$ = Rs. 12,800

r = 10% p.a.

t = 3 years

$I_{1}$ = $\frac{Prt}{100}$ = $\frac{12800*10*1}{100}$ = Rs. 1280

$A_{1} = P_{1} + I_{1}$ = 12800 + 1280

$A_{1} =$ Rs. 14080
