    Explanation

    Let the simple interest be Rs. x Principal sum = Rs. 4,800 Rate of interest = 8.5% p.a. = 17/2 % p.a. Time period = 2 years 3 months = 23122\frac{3}{{12}} year = 9/4 year S.I.  =P  ×R  ×T100{\rm{S}}.{\rm{I}}.{\rm{\;}} = \frac{{P\; \times R\; \times T}}{{100}} ⇒S.I.  =4800  ×172  ×94100\Rightarrow {\rm{S}}.{\rm{I}}.{\rm{\;}} = \frac{{4800\; \times \frac{{17}}{2}\; \times \frac{9}{4}}}{{100}} Thus, S.I.= Rs. 918 Therefore, the simple interest = Rs. 918.
