Question

find the amount to be paid at the end of 3 years in principal = i,200 at 12% p.a.

Answer 1

Principal, R = Rs. 1200
Rate, R = 12 % p.a.
Time, T = 3 Years
$\mathrm{intrest}=\frac{\mathrm{P}\times \mathrm{R}\times \mathrm{T}}{100}=\frac{1200\times 12\times 3}{100}=12\times 12\times 3=\mathrm{Rs}.432$

Amount, A = P + I = 1200 + 432 = Rs. 1632
