Conclusion : 1 Mark

His savings = His earning - total expenditure

His savings$=80-(13\frac{3}{5}+12\frac{1}{2}+4\frac{2}{5})$
$=80-(\frac{68}{5}+\frac{25}{2}+\frac{22}{5})$
$=80-\left(\frac{136+125+44}{10}\right)$
$=80-\frac{305}{10}$
$=\frac{800-305}{10}$
$=\frac{495}{10}$
$=49\frac{5}{10}$
His savings$=49\frac{1}{2}$
