Question

Find the amount to be paid at the 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 1

We have,

(a) $principal\left(p\right)=Rs1200$

$Rate\left(R\right)=12\%$

$Time\left(t\right)=3year$

$S.I=\frac{P\times R\times T}{100}$

$=\frac{1200\times 12\times 3}{100}$

$=Rs432$

$amount=P+S.I$

$=1200+432$

$=1632$

(b)$P=7500$

$rate\left(r\right)=5\%$

$T=3year$

$S.I=\frac{P\times R\times T}{100}$

$=\frac{7500\times 5\times 3}{100}$

$=1125$

$amount=7500+1125$

$=8625$
