 \:  \:  \:  \:  \:  \sf{cost \: of \: 1kg \: rice = 40 \frac{1}{2}}  \\

 \:  \:  \:   \:  \: \sf{cost \: of \: 1kg \: rice =  \frac{81}{2}}  \\

 \:  \:  \sf{cost \: of \: 3 \frac{1}{3}kg \: rice  =  \frac{81}{2}  \div  \frac{3}{10}}

 =  > \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \frac{81}{2}  \times  \frac{10}{3}  \\

  \:  \:  \:  \:  \:  \:  \:  =  >  \:  \:  \:  \:  \: \:  \:  27 \times 5

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  >  \: \sf{13 5rs}
