True-breeding red-eyed Drosophila flies with plain thorax were crossed with pink-eyed flies with striped thorax.

$\begin{array}{ccc}\mathrm{Red-eye} \mathrm{and plain} thorax & \mathrm{X }& \mathrm{P}\mathrm{i}\mathrm{n}\mathrm{k-}\mathrm{e}\mathrm{y}\mathrm{e} \mathrm{and} \mathrm{striped} thorax\end{array}$

The ${\mathrm{F}}_1$ flies were then test crossed against the double recessive.

The following F2 generation resulted from the cross:
 

80	16	12	92
Red-eye	Red-eye	Pink-eye	Pink-eye
Plain thorax	Striped thorax	Plain thorax	Striped thorax

What percentage number of recombinants resulted from the test cross?
