⇝Solution :-

❒ Here :

${\red{\rightarrowtail}{\bf{Total \: garments = 850}}}$

${\red{\rightarrowtail}{\bf{\% \: of \: garments \: having \: faults = 1.5\%}}}$

❒ Than :

${\large{:{\longmapsto{\bf{ \frac{1.5}{100} \times850 }}}}}$

${\large{:{\longmapsto{\bf{ \frac{15}{100 \times 10} \times 850 }}}}}$

${\large{:{\longmapsto{\bf{ \frac{15}{100 0} \times 850 }}}}}$

${\large{:{\longmapsto{\bf{ {\cancel\frac{12750}{100 0} }}}}}}$

${\large{\pink{:{\longmapsto{\underline{\overline{\boxed{\bf{ 12.75 \: or \: 13 garments }}}}}}}}}$

❒ Hence :

➻ About 13 garments have faults.
