Final answer:
The salesman's total income with a monthly salary of Rs 12,500 and a commision of 0.5% on Rs 7,20,000 in sales would be Rs 16,100. To earn Rs 20,000 in the following month, he would need to make sales amounting to Rs 15,00,000.
Step-by-step explanation:
The subject in question involves the calculation of income with a fixed salary and addition of a commission based on sales. To answer the first part of the question, we need to calculate the total income of a salesman whose monthly salary is Rs 12,500 and receives an additional commission of 0.5% on the monthly sales. In this case, for a sale of Rs 7,20,000:
- Calculate the commission: Rs 7,20,000 * 0.5% = Rs 3,600.
- Add the commission to the fixed salary: Rs 12,500 + Rs 3,600 = Rs 16,100.
The salesman’s total income for that month would be Rs 16,100.
To answer the second part of the question, we need to find out what total sales he needs to achieve to earn Rs 20,000 in a month, knowing his fixed salary and the commission rate:
- Subtract the fixed salary from the desired total income: Rs 20,000 - Rs 12,500 = Rs 7,500.
- Divide the remaining amount by the commission rate to find the required sales: Rs 7,500 / 0.5% = Rs 15,00,000.
The salesman would need to make sales totalling Rs 15,00,000 the next month to earn a total income of Rs 20,000.
