Answer:
rs 31.25/kg
Step-by-step explanation:
He paid rs 25 per kg.
He bought 125 kg.
First, we find out the amount he paid.
total cost = unit cost * weight
total cost = (rs 25)/kg * 125 kg
total cost = rs 3125
He spent a total of rs 3125 buying the 125 kg of potatoes.
He wants to make a 20% profit on his cost, so the profit is
20% * rs 3125 =
= 0.2 * rs 3125
= rs 625
The amount of profit he wants is rs 625.
He must add the profit to his cost to calculate the total selling price.
rs 3125 + rs 625 = rs 3750
He must sell all the good potatoes for a total of rs 3750.
5 kg of potatoes were bad.
125 kg 5 kg = 120 kg
He can only sell 120 kg of good potatoes.
Now we calculate the selling price per kg.
(rs 3750)/(120 kg) = rs 31.25/kg
Answer: rs 31.25/kg
