Commission Calculation for Mr. Y

Given Information:
- Mr. Y consigned 800 packets of toothpaste to Z.
- The cost price of each packet was `900.
- Mr. Y spent `15,000 as cartage.
- He sold 740 packets at a profit of 25% of the sale.
- Half of the sales were credit sales.
- Mr. Y was entitled to a 2% commission on sales plus 1% del-credere commission.

Calculating the Total Cost:
To calculate the total cost, we need to consider the cost price of each packet and the cartage expenses.

Cost price of 800 packets = 800 * `900 = `720,000
Total cost = Cost price of 800 packets + Cartage expenses = `720,000 + `15,000 = `735,000

Calculating the Total Sales:
To calculate the total sales, we need to consider the selling price and the number of packets sold.

Profit on each packet = 25% of the sale = 25/100 * Cost price = 25/100 * `900 = `225
Selling price of each packet = Cost price + Profit on each packet = `900 + `225 = `1,125
Total sales = Selling price of each packet * Number of packets sold = `1,125 * 740 = `834,000

Calculating the Commission:
Mr. Y is entitled to a 2% commission on sales plus 1% del-credere commission.

Commission on sales = 2/100 * Total sales = 2/100 * `834,000 = `16,680
Del-credere commission = 1/100 * Total sales = 1/100 * `834,000 = `8,340

Total Commission = Commission on sales + Del-credere commission = `16,680 + `8,340 = `25,020
