Correct Answer: 266 units
Explanation:
Per year income = Tk. 75,000
per year salay = Tk. 45,000
After subducting = Tk. 30,000
He must earn Tk. 30,000 by sales commission.
At 15% commission on sales
At Tk. 100 makes sales commission = Tk. 15
At Tk. 750 makes sales commission = Tk. $\frac{15×750}{100}$
= $\frac{225}{2}$
He earns Tk. $\frac{225}{2}$ commisswn on = 1 unit sales
He earns Tk. 30,000 commission on =$\frac{30000\cdot2}{225}$
= $\frac{800}{3}$ unit = 266 units
