Question

At what rate percent per annum a sum of Rs.$1,800$ will become Rs. $2,700$ in $10$ years?

• A. $5\%$
• B. $6\%$
• C. $10\%$
• D. $8\%$

Answer 1

The correct option is A $5\%$

$P=Rs.1,800,A=Rs.2,700,T=10years$
$I=A-P=2700-1800=Rs.900$ ,

$R=\frac{100\times I}{P\times T}=\frac{100\times 900}{1800\times 10}=5$%
