Question 15 of 17intermediate🔧 ApplyNumerical4 marks

I run a small dosa cart and my expenses are as follows: Rent for the dosa cart is ₹5000 per day. The cost of making one dosa (including all the ingredients and fuel) is ₹10. (i) If I can sell 100 dosas a day, what should be the selling price of my dosa to make a profit of ₹2000? (ii) If my customers are willing to pay only ₹50 for a dosa, how many dosas should I aim to sell in a day to make a profit of ₹2000?

(i)
Answer

The selling price should be ₹80 per dosa.

(ii)
Answer

175 dosas should be sold per day.

Explanation

(i) Total cost = 5000 + 100×10100 \times 10 = 6000. Required revenue = 6000 + 2000 = 8000. Price = 8000/100 = ₹80. (ii) Profit equation: 50n - 5000 - 10n = 2000, giving 40n = 7000, n = 175.
