Find the amount to be paid at end of 3 years in each case: |
(a) Principal = Rs 1,200 at 12% p.a. |
(b) Principal = Rs 7,500 at 5% p.a. |
Answer:
(a) We have, P = Rs 1,200, R = 12% p.a. and T = 3 years. Now, \[S.I.\text{ }=~\frac{P\times R\times T}{100}\] \[S.I.\text{ }=Rs\,~\left( \frac{1200\times 12\times 3}{100} \right)=Rs\,\,432\] Now, Amount = P + S.I. = Rs (1200 + 432) = Rs 1,632 2 (b) We have, P = Rs 7,500, R = 5% p.a. and T = 3 years \[S.I.\text{ }=~\frac{P\times R\times T}{100}\] \[S.I.\text{ }=Rs\,~\left( \frac{7500\times 5\times 3}{100} \right)=Rs\,\,1,125\] Now, Amount = P + S.I. = Rs (7500 + 1125) = Rs 8,625
