Question 70

A dealer sold 6 sewing machines for ₹63,000 with a profit of 5%. For how much should he sells 8 machines if he intends to earn 15% profit?

Solution

Selling price 6 sewing machines = 63,000

Profit = 5%

Cost price 6 sewing machines = $$\frac{63000}{105} \times 100 = 60000$$

Cost price 1 sewing machine = 60000/6 = 10000

After 15% profit, selling price of 1 sewing machine = 10000 $$\times \frac{115}{100} = 11500$$

Selling price of 1 sewing machine = 11500 $$\times$$ 8 = Rs. 92,000
