100 oranges are bought at the rate of Rs. 350 and sold at the rate of Rs. 48 per dozen. The percentage of profit or loss is:

Answer 1

cp of 100 oranges =rs350
cp of 1 orange =3.50 rs
sp of 12 oranges =48rs
sp f 1 orange =4 rs
sp of 100 oranges =400 rs
profit =50 rs
profit %= 50 /350 ×100
profit %= 14.28 %approximately

Answer 2

→CP of 100 oranges = ₹ 350

CP of 1 orange = 350/100 = ₹ 3.5

→SP of 12 oranges = ₹ 48

SP of 1 orange = 48/12 = ₹4

→Gain = 4.0-3.5 = 0.5

→Gain percent = [(gain×100)/CP]%

= (0.5×100/3.5)%

=100/7%

= 14 2/7 %
