A) \[1\frac{1}{3}\]
B) \[1\frac{1}{2}\]
C) \[2\frac{1}{3}\]
D) \[2\frac{1}{2}\]
Correct Answer: B
Solution :
Let the time be 'n' years. Then, \[800\times {{\left( 1+\frac{5}{100} \right)}^{2n}}=926.10\] \[\Rightarrow \] \[{{\left( \frac{21}{20} \right)}^{2n}}={{\left( \frac{21}{20} \right)}^{3}}\] \[\Rightarrow \] \[2n=3\Rightarrow n=\frac{3}{2}\] \[\therefore \] \[n=1\frac{1}{2}\] yearsYou need to login to perform this action.
