Question

a vendor brought 15 orange at Rs 36 for 5 oranges and sold all of them at four oranges for Rs 45. How much did the vendor earn or loss in the transaction?​

Answer 1

Step-by-step explanation:

Since, cost price of the 5 oranges = 36 rupees,

⇒ Cost price of 15 oranges = 3×36 = 108 rupees,

Hence, the total cost price = 108 rupees

Also, the selling price of the 4 oranges = 45 rupees,

⇒ The selling price of the 1 orange = 45/4 = 11.25 rupees,

⇒ The selling price of the 15 oranges = 15 × 11.25 = 168.75 rupees,

Thus, the total selling price = 168.75 rupees

Hence the total earning = selling price - cost price

= 168.75 - 108

= 60.75 rupees.
