${\mathrm{A}}_1$	${\mathrm{B}}_1$	${\mathrm{C}}_1$	${\mathrm{D}}_1$
${\mathrm{A}}_2$	${\mathrm{B}}_2$	${\mathrm{C}}_2$	${\mathrm{D}}_2$
${\mathrm{A}}_3$	${\mathrm{B}}_3$	${\mathrm{C}}_3$	${\mathrm{D}}_3$
${\mathrm{A}}_4$	${\mathrm{B}}_4$	${\mathrm{C}}_4$	${\mathrm{D}}_4$

Race between A’s, B’s, C’s, D’s group [4races]
Let Say ${\mathrm{A}}_1$ , ${\mathrm{B}}_1$ , ${\mathrm{C}}_1$ , ${\mathrm{D}}_1$ are fastest in the group. [1 race] ×Let Say ${\mathrm{A}}_1$ → $1^{\mathrm{st}}$ fastest ${\mathrm{B}}_1\to 2^{\mathrm{nd}}$
Then Can not be first fast runner. Only possibility for second fast runner be ${\mathrm{A}}_2,{\mathrm{B}}_1$ [1 race] Total races $=4+1+1=6$
