$\underline{\huge{\textbf{Question}}}$:

Find the amount to be paid at the end of the 3 years if the principal amount is 1200 at 10% per
annum.

$\underline{\huge{\textbf{Answer}}}$:

Given,
Time period T = 3 years
Principal amount P = 1200 Rs.
Rate of Interest R = 10%

$\underline{\large{\textbf{Step-1}}}$:
Find Simple Interest on Rs. 1200 at 10% per annum

$Simple\: Interest(SI)=\dfrac{P \times T \times R}{100}$

Substituting Values

$\implies SI = \frac{1200 \times 3 \times 10}{100}$

$\implies SI = 12 \times 3 \times 10$

$\implies SI = 360 Rs.$

Simple Interest on Rs. 1200 at 10% per annum = Rs. 360

$\underline{\large{\textbf{Step-2}}}$:
Find Amount to be paid at the end of 3 years.

Amount to be paid = Principal + Simple Interest

$\implies Amount\: to\: be\: paid = 1200 + 360$

$\implies Amount\: to\: be\: paid = 1560\: Rs$

Therefore,
Amount to be paid = Rs. 1560
