Question

) Mrs. Gurung bought 50 kg of tomatoes for Rs 1,900 from a tunnel farm and paid Rs 2 per kg for transporting it to her shop. She found that 10% of the tomatoes were damaged. She sold the remaining quantity for Rs 60 per kg.

(i) What is the total cost price of tomatoes?
(ii)How many kilograms of the tomatoes were damaged? (iii) Calculate her profit or loss percent in the total transaction​

Answer 1

i) Rs2000

ii) 50kg

iii) 25.9%

Explanation:

Set up a table, hopefully on a spreadsheet, and enter the information, with units. See the attached table.

We can calculate the total cost of the tomatoes by adding the amount Mrs. Gurung paid (50kg)*(Rs2/kg) and adding the shipping cost (50 kg)*(Rs2/kg) = Rs100 for a total cost of Rs2000 (yellow cell).

Now deduct the 10% loss: (50kg) - (50kg)*(0.10) = 45 kg available to sell (5kg loss, green cell).

The remaining 45kg are sold for Rs60/kg. That is a total sales of (45kg)*(Rs60/kg) = Rs2700.

Rs2700 - Rs200 = Rs700 is the total profit. Divide that by the total sales values to obtain percent profit based on the entire transaction of Rs2700 to yield a profit percentage of 25.9% (orange cell).
