A salesman is allowed an 11% commission on the total sales made by him and a bonus of 1% on the sale over Rs. 15,000/-. If the total earning of the salesman is Rs. 5,850/-, then find the amount of total sales (in Rs.).

50000

Let total sales be x

(x × 11%) + (x - 15000) × 1% = 5850

11%x + 1%x - 150 = 5850

12%x = 6000

\(\frac{12}{100}\)x = 6000

x = 50,000
