Question

a vendor purchased 50 dozens of bananas for rs 450 out of these 60 bananas were found to be defective and could not be sold at what rate per dozen should he sell the remaining bananas to make a profit of 10%

Answer 1

price of 50 dozen banana = Rs 450

total bananas = 50 x 12 = 600

diffective = 60

Good once = 600 - 60 = 540/12 = 20dozens

Selling price per dozen = x

x/450 = 110/100 (orginal price + profit = 100+10 = 110)

x = 450x 110/100

x = Rs495

So he should sold a dozen banana in the rate of Rs495
