Question

A vendor purchased bananas at 40 per dozen and sold them at 10 for 36. Find his gain
or loss per cent.​

Answer 1

Answer:Cost Price = 40/12 = Rs. 3.33/ banana  

Selling Price   = 36/10 = Rs 3.6/ banana

Therefore, It is 43.2 for 12 bananas .

Profit= SellingPrice−CostPrice  = 43.2−40=3.2

Therefore, Profit %=  3.2 /40 x 100 =8% profit
