This Question has 3 answers.
Let the man buy $\large 60$ oranges (LCM of $\large 20$ and $\large 30$) of each kind.
CP of the $\large 60$ oranges of the first kind=$ \large \frac{60}{20}\times 60=120 Rs.$
Total CP of $\large 120 $oranges $\large =(180+120)Rs.= 300$
Their SP=$\large \frac{60}{25}\times 120=288$ Rs.
$ \large Loss=(300-288)= 12$ Rs.
$\large \therefore$ Loss percent= $\large \frac{12}{300}\times 100= 4%$
