A) \[5\frac{1}{2}%\]
B) 8%
C) 7%
D) 6%
Correct Answer: C
Solution :
Principal P = Rs. 1600 t = 2 yr 3 months \[=\left( 2+\frac{3}{12} \right)\,\,\text{yr}=\left( 2+\frac{1}{4} \right)\,\,\text{yr}=\frac{9}{4}\,\,\text{yr}\] SI = Rs. 252 r = Per cent rate of interest per annum \[r=\frac{100}{pt}\times \text{SI}\] \[r=\frac{100\times 252}{1600\times \frac{9}{4}}\]\[\Rightarrow \]\[r=\frac{100\times 4\times 252}{1600\times 9}\]\[\Rightarrow \]\[r=7%\]You need to login to perform this action.
