A customer asks for the production of x number of goods. The company produces y number of goods daily. Out of which z% are units for sale. The order will be completed in :
A
$$ {\frac{x}{{100y \times \left( {1 - z} \right)}}} \,{\text{days}}$$
B
$$ {\frac{{100yz}}{x}} \,{\text{days}}$$
C
$$ {\frac{{100x}}{{\left( {100 - z} \right)y}}} \,{\text{days}}$$
D
$$\frac{{100}}{{y \times \left( {z - 1} \right)}}\,{\text{days}}$$
E
Cannot determined
Correct Answer: $$ {\frac{{100x}}{{\left( {100 - z} \right)y}}} \,{\text{days}}$$
$$\eqalign{ & {\text{Daily}}\,{\text{supply}}, \cr & = \left( {100 - z} \right)\% \,{\text{of}}\,y \cr & = \frac{{ {\left( {100 - z} \right)y} }}{{100}} \cr & {\text{Thus,}}\,{\text{required}}\,{\text{number}}\,{\text{of}}\,{\text{days}} \cr & = {\frac{{ {100x} }}{{\left( {100 - z} \right)y}}} \cr} $$
