Gain %= gain/cost price* 100
loss%=loss/c.p*100

as he bought 20 for 56, one orange =56/20=2.8
he sells 12 for 35 ,so one orange=35/12=2.9
so profit = sell-bought=2.9-2.8=0.1

so the profit is 0.1 for one orange
for 12 orange profit is 12*0.1=0.12
profit percentage=0.12/35*100=0.35
therefore the profit percentage is 0.35%

C.P of 20 oranges = 56
so, C.P of 1 orange = 56/20 = 2.80
S.P of dozen oranges = 35
so, S.P of 1 orange = 35/12 = 2.92
since, S.P>C.P
Profit = S.P - C.P= 2.92-2.80= 0.12
Profit %= (profit/C.P )* 100%
=(0.12/2.80)*100%
=(12/280)*100%
=4.29%
