A partner gets five percent commission on sales and ten percent commission on profit. Sales are two lakh rupees and profit before commission is fifty thousand rupees. What is total commission if profit commission is on before commission basis?

Correct answer: Fifteen thousand rupees

The direct answer is option A: ₹15,000. There are two separate commissions. Sales commission = 5% of sales = 5/100 × ₹200,000 = ₹10,000. The question explicitly says that the profit commission is calculated on profit before commission. Therefore profit commission = 10% of ₹50,000 = ₹5,000. Total commission = sales commission + profit commission = ₹10,000 + ₹5,000 = ₹15,000. Option A is correct. Option B, ₹10,000, counts only the sales commission and leaves out the profit commission. Option C, ₹20,000, overstates the total and does not follow either stated percentage calculation. Option D, ₹5,000, counts only the profit commission and leaves out the sales commission. The phrase “before commission basis” is important: it means we use the given ₹50,000 directly, rather than trying to calculate commission on a reduced profit or solving a denominator formula. Always calculate each commission separately, then add them. Memory cue: sales percentage uses sales; profit percentage uses the stated profit base.
