A) 25%
B) 30%
C) 45%
D) 50%
Correct Answer: D
Solution :
Suppose P = Rs. 100 and amount A = Rs. 225 \[A=P{{\left( 1+\frac{r}{100} \right)}^{r}}\] \[\Rightarrow \]\[225=100{{\left( 1+\frac{r}{100} \right)}^{2}}\] \[\Rightarrow \]\[\frac{225}{100}={{\left[ 1+\frac{r}{100} \right]}^{t}}\] \[\Rightarrow \]\[1+\frac{r}{100}=\frac{15}{10}\]\[\Rightarrow \]\[\frac{100+r}{100}=\frac{15}{10}\] \[\Rightarrow \]\[100+r=150\]\[\Rightarrow \]\[r=50%\]You need to login to perform this action.
