A) 3 years
B) 4 years
C) 5 years
D) none of these
Correct Answer: B
Solution :
First Case Interest \[=8000-6000=Rs,\text{ }2000\] Rate \[=\frac{Interest\times 100}{Principal\times Time}\] \[=\frac{2000\times 100}{6000\times 4}=\frac{25}{3}%\] Per annum Second Case Interest \[=700-525=Rs.\text{ }175\] Time \[=\frac{Interest\times 100}{\text{ }Principal\times Rate}\] \[=\frac{175\times 100}{525\times \frac{25}{3}}=\frac{175\times 100\times 3}{525\times 25}=4\]yearsYou need to login to perform this action.
