A salesman received 12% commission on the total sales made by him and a bonus of 1% on the sales over ₹ 15000/-. If the total earning of the salesman is ₹7650/-, then find the amount of total sales (in ₹).

60,000

Let total sale is Rs.X

ATQ,

(X × 12%) + (X - 15000) × 1% = 7650

(X × 12%) + (X) × 1% - 15000 × 1% = 7650

(X × 13%) - 150 = 7650

(X × 13%) = 7650 + 150 = 7800

(X × 1%) = 600

(X × 100%) = 60000
