A) 2.5%
B) 3%
C) 4%
D) 5%
Correct Answer: C
Solution :
Interest for\[1\frac{1}{2}\]yr = Rs.\[(1067.20-1012)\] = Rs. 5520 |
\[\therefore \] Interest of \[2\frac{1}{2}\]yr \[=55.20\times \frac{2}{3}\times \frac{5}{2}\]= Rs. 92 |
\[\therefore \] Principal\[=1012-92\]= Rs. 920 |
\[\therefore \] \[\text{Rate=}\frac{\text{SI }\!\!\times\!\!\text{ 100}}{\text{Principal }\!\!\times\!\!\text{ Time}}=\frac{92\times 100}{920\times \frac{5}{2}}=4%\] |
