cost price of oranges is given as Rs.26/-per dozen
seling price of 5 oranges =Rs.13
therefore,selling price of oranges= 13/5
seling price of 12 oranges =13/5×12=Rs.31.20 per dozen
seling price of oranges >cost price of oranges
so,gain occurs
gain on selling a dozen of oranges=S.P - C.P.=31.20 -26=5.20

GAIN
%=gain ×100 =5.2 ×100=52 × 100=20%
             C.P             26          260

there fore, the required gain % is =20%
