A) \[5\frac{1}{2}\,yr\]
B) \[6\frac{1}{2}\,yr\]
C) \[7\,yr\]
D) \[7\frac{1}{2}\,yr\]
Correct Answer: D
Solution :
Let the principal \[=Rs.\,P\] \[\therefore \] Simple interest \[=Rs.\,\frac{9P}{16}\] \[\therefore \] \[\frac{9P}{16}=\frac{P\times r\times t}{100}\] \[\Rightarrow \] \[{{t}^{2}}=\frac{900}{16}\] \[\Rightarrow \] \[t=\frac{30}{4}=7\frac{1}{2}yr\]You need to login to perform this action.
