Question

Ramlal bought oranges at r .30 per dozen .He had to sell them at a loss of 5 % .Find the selling price

Answer 1

Cost Price of a dozen oranges = Rs 30

Find the loss:

loss = percentage loss x cost price

5% loss = 5% x 30 = 0.05 x 30  = Rs 1.50

Find the selling price:

Selling Price = Cost Price - loss

Rs 30 - Rs 1.50 = Rs 28.50

Answer: The selling price of the dozen of oranges is Rs 28.50

Answer 2

Given

cost price is Rs 30 per dozen

per dozen = 12 ..

12 oranges = Rs 30

1 orange = 30 ÷ 12 = Rs 2.5

Finding loss -

Given loss = 5%

2.5 x 5/100 = 0.125

loss = 0.125

Finding selling price -

selling price = cost price - loss

= 2.5 - 0.125 = 2.375 .

= 12 x 2.375 = 28.5

Selling price per orange is Rs 2.375.

Selling price per dozen is 12 Rs 28.5
